Assembly And Installation

Figure 1
Connecting K1W Series (wall mount) to Wall
- Determine mounting location on wall.
- Use a stud finder to locate 2" x 4" wood stud.
- Use wall bracket (E) to mark and drill two 1/8" x 2 1/2" holes in wall at desired mounting location. (See Figure 1)
IMPORTANT ! : Only top and bottom holes of wall bracket (E) must be used to attach bracket to wall as shown in Figure 1. Do NOT use any other holes to secure bracket to wall!
- Use two 1/4-2 1/2" hex head lag screws (F) and two 1/4" washers (G) to install wall bracket (E) onto wall. (See Figure 1)
IMPORTANT ! : Over tightening screws (F) may cause bracket to compress into soft wall surface resulting in difficult mount installation or improper engaging of set screw in Step 6.
-
Hang monitor arm (A) over wall bracket (E). (See Figure 1)
-
Secure monitor arm to wall bracket (E) by tightening set screw. Ensure set screw engages back side of wall bracket (E) to properly secure mount. (See Figure 1)

NOTE: K1S220 has an OFBU bracket instead of an OFBLU bracket. Proceed to K1S220 section if installing K1S220.
K1S120 and K1S22H
- Determine mounting location.
- Hang OFBLU bracket onto slat wall at desired mounting location by inserting the upper mounting plate into wall track. (See Figure 2)
- Let lower mounting plate rest against slat wall.

Figure 2
- Using 5/32" hex key (N), turn adjustment screw clockwise to lower mounting plate until it is able to easily slide into wall track. (See Figure 3)
- Using 5/32" hex key (N), turn adjustment screw counterclockwise to raise lower mounting plate until bracket is fully secured to slat wall. (See Figure 3)

Figure 3
K1S220
- Verify mounting brackets on OFBU bracket can move freely. (See Figure 4)

Figure 4
- Locate desired installation location and slide upper mounting plate into wall making sure bracket is seated in channel bottom. (See Figure 5)
- Let lower mounting plate rest against wall.
- Using 1/2" socket, tighten tension hex head bolt until lower mounting plate slides into channel in wall and continue tightening until resistance is felt. (See Figure 5)

Figure 5
- Tighten two upper and lower button head cap screws to secure OFBU bracket to wall. (See Figure 6)

Figure 6
