Installation instructions

• HOW TO SET UP A NINJA OBSTACLE COURSE?
Step 1: Where to Slackline?
Picking a place to slackline is mostly based on personal preference. To set up the ninja line, two objects will be needed to tie it into place (typically trees).
MATTERS NEEDING ATTENTION:
Do not use buildings or playground structures (unless specifically built for slackline), live power/telephone poles, dead trees or stumps, trees with rot, disease, structural cracks, excessive lean, exposed roots, or trees in boggy, wet, sandy, loose soil. This is only a partial list. You must use your good judgment in determining what is not an appropriate anchor point. If in doubt, please contact us.
Step 2: install tree protectors. They can not only protect trees, but also reduce the wear of the slackline.
Installation height: more than 2.2m (7.2ft) is recommended
Of course, this value is not absolute. You can appropriately adjust the installation height of the slackline according to your child's height.





Step 3: Install the main line and ratchet line on the installed tree protectors.
Step 4: Install the hanging buckles to the main line.
It is recommended to install a hanging buckle every 11.8-15.8in.
![graph LR A["Device with lid"] --> B["Internal Combustion"] B --> C["Backfilling"]](/content/2026/04/736592/images/6b57f498730c0e2df125d6e5296fce674fc1895ec7e1363cf8d7d4cc1e99d5ea.jpg)
If you are unable to determine the exact location during installation, you can straighten the main line and put it on the ground. Then measure with a tape measure and mark on the main line with a marker pen.
Step 5: Use the ratchet to tighten the main line of the slackline.
Tip: if you need to adjust the position of your hanging buckles, you must loosen the ratchet line before adjustment. Because the friction between the buckles and the main line is very large when the main line is tightened, you can't adjust the position of the hanging buckles.
Step 6: Use contact buckles to hang all accessories on the hanging buckle and tighten it.
Please note that after installing the accessories, you need to test their reliability. We sincerely hope you enjoy your ninja slackline kit as much as possible. Have fun!
• HOW TO USE THE RATCHET LINE

- First, close the ratchet and thread the webbing through the upper hole in the middle of the ratchet. If the position of the hole is not above, it can be adjusted to the top by opening and closing the ratchet.
- Pull the webbing down until it is as tight as possible. Then tighten the webbing with one hand and hold the handle of the ratchet with the other hand. Tighten the webbing by continuously opening and closing the ratchet until you can't pull the handle of the ratchet. Note: please make sure your ratchet is closed when it is finally tightened.

- When you are ready to stow the slackline kit, you can pull the switch marked in the figure outward and open the handle of the ratchet to about 180° at the same time. After hearing the "bang", you can pull the webbing out of the ratchet and put it away.

Step 3: Install the main line and ratchet line on the installed tree protectors.
Step 4: Install the hanging buckles onto the main line.
It is recommended to install a hanging buckle every 11.8-15.8 inches.

If you are unable to determine the exact location during installation, you can straighten the main line and place it on the ground. Then measure with a tape measure and mark the main line with a marker pen.
Step 5: Use the ratchet to tighten the main line of the slackline.
Tip: If you need to adjust the position of your hanging buckles, you must loosen the ratchet line before adjustment. Because the friction between the buckles and the main line is very large when the main line is tightened, you cannot adjust the position of the hanging buckles.
Step 6: Use contact buckles to hang all accessories on the hanging buckle and tighten it.
Please note that after installing the accessories, you need to test their reliability. We sincerely hope you enjoy your ninja slackline kit as much as possible. Have fun!
• HOW TO USE THE RATCHET LINE

- First, close the ratchet, and thread the webbing through the upper hole in the middle of the ratchet. If the position of the hole is not above, it can be adjusted to the top by opening and closing the ratchet.
- Pull the webbing down until it is as tight as possible. Then, with one hand, tighten the webbing, and with the other hand, hold the handle of the ratchet. Tighten the webbing by continuously opening and closing the ratchet until you can no longer pull the handle. Note: make sure the ratchet is closed when it is finally tightened.

- When you are ready to stow the slackline kit, pull the switch marked in the figure outward and simultaneously open the handle of the ratchet to about 180°. After hearing a "bang", you can pull the webbing out of the ratchet and put it away.

Step 1: Where to Slackline?
Choosing a place to slackline is mostly based on personal preference. To set up the ninja line, you will need two objects to tie it to (typically trees).
▲ MATTERS NEEDING ATTENTION:
Do not use buildings or playground structures (unless specifically built for slackline), live power/telephone poles, dead trees or stumps, trees with rot, disease, structural cracks, excessive lean, exposed roots, or trees in boggy, wet, sandy, or loose soil. This is only a partial list. You must use your good judgment in determining what is not an appropriate anchor point. If in doubt, please contact us.
Step 2: Install tree protectors. They not only protect the trees but also reduce wear on the slackline.

Installation height: Generally, we recommend that the height difference between the two slacklines be slightly less than: your child's height + half the length of the balance belt, and the bottom slackline should be about 23.6 inches from the ground. Of course, you can adjust the height according to your actual situation.



Step 4: Attach the ratchet line to another tree or solid post. Put the ratchet protector on first. Then use the ratchet to tighten the main line of the slackline. Cover the protective sleeve onto the ratchet again. (The protective sleeve is used for 2-inch slackline.)

Picking a place to slackline is mostly based on personal preference. To set up the ninja line, two objects will be needed to tie it into place (typically trees).
MATTERS NEEDING ATTENTION:
Do not use buildings or playground structures (unless specifically built for slackline), live power/telephone poles, dead trees or stumps, trees with rot, disease, structural cracks, excessive lean, exposed roots, or trees in boggy, wet, sandy, loose soil. This is only a partial list. You must use your good judgment in determining what is not an appropriate anchor point. If in doubt, please contact us.
Step 2: Install tree protectors. It can not only protect trees, but also reduce the wear of slackline.
Installation height: more than 2.2m (7.2ft) is recommended.
Of course, this value is not absolute. You can adjust the installation height of the slackline appropriately according to your child's height.





Step 3: Install the main line and ratchet line on the installed tree protectors.
Step 4: Install the hanging buckles to the main line.
It is recommended to install a hanging buckle every 11.8-15.8in.

If you are unable to determine the exact location during installation, you can straighten the main line and put it on the ground. Then measure with a tape measure and mark on the main line with a marker pen.
Step 5: Use the ratchet to tighten the main line of the slackline.
Tip: if you need to adjust the position of your hanging buckles, you must loosen the ratchet line before adjustment. Because the friction between the buckles and the main line is very large when the main line is tightened, you can't adjust the position of the hanging buckles.
Step 6: Use contact buckles to hang all accessories on the hanging buckle and tighten it.
Please note that after installing the accessories, you need to test their reliability. We sincerely hope you enjoy your ninja slackline kit as much as possible. Have fun!
• HOW TO USE THE RATCHET LINE

- First, close the ratchet and thread the webbing through the upper hole in the middle of the ratchet. If the position of the hole is not above, it can be adjusted to the top by opening and closing the ratchet.
- Pull the webbing down until it is as tight as possible. Then tighten the webbing with one hand and hold the handle of the ratchet with the other hand. Tighten the webbing by continuously opening and closing the ratchet until you can't pull the handle of the ratchet. Note: please make sure your ratchet is closed when it is finally tightened.

- When you are ready to stow the slackline kit, you can pull the switch marked in the figure outward and open the handle of the ratchet to about 180° at the same time. After hearing the "bang", you can pull the webbing out of the ratchet and put it away.

- Pull the webbing down until it is as tight as possible. Then tighten the webbing with one hand and hold the handle of the ratchet with the other hand. Tighten the webbing by continuously opening and closing the ratchet until you can't pull the handle of the ratchet. Note: please make sure your ratchet is closed when it is finally tightened.

- When you are ready to stow the slackline kit, you can pull the switch marked in the figure outward and open the handle of the ratchet to about 180° at the same time. After hearing the "bang", you can pull the webbing out of the ratchet and put it away.

• HOW TO SET UP A NINJA OBSTACLE COURSE?
Step 1: Where to Slackline?
Picking a place to slackline is mostly based on personal preference. To set up the ninja line, two objects will be needed to tie it into place (typically trees).
MATTERS NEEDING ATTENTION:
Do not use buildings or playground structures (unless specifically built for slackline), live power/telephone poles, dead trees or stumps, trees with rot, disease, structural cracks, excessive lean, exposed roots, or trees in boggy, wet, sandy, loose soil. This is only a partial list. You must use your good judgment in determining what is not an appropriate anchor point. If in doubt, please contact us.
Step 2: Install tree protectors. They not only protect the trees but also reduce wear on the slackline.
Installation height: more than 2.2m (7.2ft) is recommended.
Of course, this value is not absolute. You can adjust the installation height of the slackline appropriately according to your child's height.





Step 3: Install the main line and ratchet line on the installed tree protectors.
Step 4: Install the hanging buckles onto the main line.
It is recommended to install a hanging buckle every 11.8-15.8 inches.
![graph LR A["Device Icon"] --> B["Close-up of Belt Buck"] B --> C["Close-up of Belt Buck"]](/content/2026/04/736592/images/8a4494aa05606ef9ddc82ec78e6da48149c5ad8c6e9c6a41529123aa74e7c6c5.jpg)
If you are unable to determine the exact location during installation, you can straighten the main line and place it on the ground. Then measure with a tape measure and mark the main line with a marker pen.
Step 5: Use the ratchet to tighten the main line of the slackline.
Tip: If you need to adjust the position of your hanging buckles, you must loosen the ratchet line before adjustment. Because the friction between the buckles and the main line is very large when the main line is tightened, you cannot adjust the position of the hanging buckles.
Step 6: Use contact buckles to hang all accessories on the hanging buckle and tighten them.
Please note that after installing the accessories, you need to test their reliability. We sincerely hope you enjoy your ninja slackline kit as much as possible. Have fun!
• HOW TO USE THE RATCHET LINE

- First, close the ratchet and thread the webbing through the upper hole in the middle of the ratchet. If the hole is not positioned at the top, you can adjust it by opening and closing the ratchet.
- Pull the webbing down until it is as tight as possible. Then tighten the webbing with one hand while holding the ratchet handle with the other. Tighten the webbing by continuously opening and closing the ratchet until you can no longer pull the handle. Note: Make sure the ratchet is closed when it is finally tightened.

3. When you are ready to stow the slackline kit, pull the switch marked in the figure outward and open the ratchet handle to about 180° at the same time. After hearing a "bang", you can pull the webbing out of the ratchet and put it away.

Step 2: Install tree protectors. They not only protect the trees but also reduce wear on the slackline.
Step 3: Attach the main line to a tree or solid post.
Installation height: Generally, we recommend that the height difference between the two slacklines be slightly less than your child's height plus half the length of the balance belt, and the slackline at the bottom should be about 23.6 inches from the ground. Of course, you can adjust the height according to your actual situation.



Step 4: Attach the ratchet line to another tree or solid post. Put the ratchet protector on first. Then use the ratchet to tighten the main line of the slackline. Cover the protective sleeve onto the ratchet again. (The protective sleeve is used for 2-inch slacklines.)

Recommended installation height: more than 2.2 m (7.2 ft).
Of course, this value is not absolute. You can adjust the installation height of the slackline according to your child's height.


Step 3: Install the main line and ratchet line on the installed tree protectors.
Step 4: Install the hanging buckles onto the main line.
It is recommended to install a hanging buckle every 11.8–15.8 in.
![graph LR A["Device with sensor"] --> B["Valve with red curved arrows"] B --> C["Belt drive mechanism"]](/content/2026/04/736592/images/2a93edd3d11576db0e274d89f03d06da4c7d38238578f079d37718ff53a4b5ed.jpg)
If you cannot determine the exact location during installation, you can straighten the main line and place it on the ground. Then measure with a tape measure and mark the main line with a marker pen.
Step 5: Use the ratchet to tighten the main line of the slackline.
Tip: If you need to adjust the position of your hanging buckles, you must loosen the ratchet line before adjustment. Because the friction between the buckles and the main line is very large when the main line is tightened, you cannot adjust the position of the hanging buckles.
Step 6: Use contact buckles to hang all accessories on the hanging buckle and tighten it.
Please note that after installing the accessories, you need to test their reliability. We sincerely hope you enjoy your ninja slackline kit as much as possible. Have fun!
• HOW TO USE THE RATCHET LINE

- First, close the ratchet and thread the webbing through the upper hole in the middle of the ratchet. If the position of the hole is not above, it can be adjusted to the top by opening and closing the ratchet.
- Pull the webbing down until it is as tight as possible. Then tighten the webbing with one hand and hold the handle of the ratchet with the other hand. Tighten the webbing by continuously opening and closing the ratchet until you cannot pull the handle of the ratchet. Note: Please make sure your ratchet is closed when it is finally tightened.

- When you are ready to stow the slackline kit, you can pull the switch marked in the figure outward and open the handle of the ratchet to about 180° at the same time. After hearing the "bang", you can pull the webbing out of the ratchet and put it away.

Step 1: Where to Slackline?
Picking a place to slackline is mostly based on personal preference. To set up the ninjaline, two objects will be needed to tie it into place (typically trees).
MATTERS NEEDING ATTENTION:
Do not use buildings or playground structures (unless specifically built for slackline), live power/telephone poles, dead trees or stumps, trees with rot, disease, structural cracks, excessive lean, exposed roots, or trees in boggy, wet, sandy, loose soil. This is only a partial list. You must use your good judgment in determining what is not an appropriate anchor point. If in doubt, contact us.
Step 2: Install tree protectors. It can not only protect trees, but also reduce the wear of slackline.
Step 3: Attach the main line to a tree or solid post.
Installation height: Generally, we recommend that the installation height difference of two slackline be slightly less than: your child's height + half of the length of the balance belt, and the slackline at the bottom is about 23.6in from the ground. Of course, you can adjust the height according to your actual situation.



Step 4: Attach the ratchet line to another tree or solid post. Put the ratchet protector on first. Then use the ratchet to tighten the main line of the slackline. Cover the protective sleeve onto the ratchet again. (The protective sleeve is used for 2-inch slackline.)
Step 5: How to use the slackline ratchet?
We introduced the use of ratchet on the right.
