Frequently Asked Questions - CTB-40 Lowel

How do I set up the legs on the CTB-40 C-stand?

Hold the stand with the shaft over your right shoulder and feet pointing down. Hold the top leg with your left hand and rotate the bottom leg 1/3 turn counterclockwise until it locks. Then, while holding the top leg, turn the middle leg 1/3 turn counterclockwise until all legs spread evenly and lock into place.

What is the maximum height of the CTB-40?

The maximum working height is 118 inches (299.7 cm).

What is the load capacity?

The load capacity is 22 lb (10 kg). Always use sandbags and ensure the load is balanced.

Can I use the CTB-40 with a grip head and grip arm?

Yes, the CTB-40 is designed to work with Lowel's Grip Head (CGH-25) and Grip Arm (CGA-40). The grip head attaches to the 5/8 in baby pin, and the arm inserts into the 5/8 in hole from the right with the T-handle facing you.

How do I attach the grip arm to the grip head?

Loosen the grip head's T-handle, insert the grip arm into the 5/8 in hole from the right, then tighten the T-handle clockwise. Ensure the T-handle faces you and the load is on the right side to prevent accidental loosening.

Does the CTB-40 have a leveling leg?

No, the CTB-40 (turtle base) does not have a leveling leg. The CSL-40 sliding-leg model is designed for leveling on uneven surfaces.

How do I remove or replace the riser section?

Remove all fixtures and accessories. Loosen the base locking knob and lift the riser out of the junior receiver. You can replace it with a 20 in riser, a junior-to-baby-pin adapter, or other 1 1/8 in junior diameter accessories.

What materials is the CTB-40 made of?

The stand is constructed from aluminum and steel with a matte black and chrome finish.

What is the warranty on the CTB-40?

Lowel offers a one-year limited warranty to the original purchaser. For warranty service, contact Tiffen Technical Support at 1-800-645-2522 or [e-mail].

How should I clean and maintain the C-stand?

USER MANUAL

Thank you for choosing Lowel.

Lowel's 40-inch C-Stand is one of the photo, video, and TV industries' standard go-to accessories in studio or on location. The 40-inch double-riser shaft is outfitted with ergonomic locking tri-knobs that offer a firm grip and secure hold. Staggered leg height design allows nesting several stands close together. Lowel C-stands are standard sized to perfectly fit on grip trucks or C-stand hangers. When combined with Lowel's grip head and grip arm, there's no better tool for supporting light fixtures and light-modifying gobos like flags, silks, and scrims.

The turtle-base model C-stand (CTB-40) features spring-loaded legs for fast setup and breakdown and for easy travel and storage. The removable base with a 1½-inch junior receiver facilitates exchanging riser sections with accessories like a stand adapter for low-angle shooting.

The sliding-leg model C-stand (CSL-40) features a movable top leg that's secured by a tri-knob. It's designed for leveling the stand on uneven surfaces like stairs, hills, and curbs.

Lowel's Grip Head (CGH-25) provides 5/8 and 3/8-inch holes for mounting grip arms and other lighting fixtures or grip equipment. The 40-inch Grip Arm (CGA-40) features a fixed 2.5-inch grip head and a pin with a flat recess that will prevent slipping or rotating when mounting small light fixtures.
