Installation (continued)

6.  Mount the first lifting bracket in the top section of the wall 

opening behind the T-track. Measure 2⅛” from the back 
(projector side) of the T-track to the back edge of the lifting 
bracket and ½” from the edge of the opening to position the 
bracket correctly. Use 1/4” x 1” lag screws to attach the bracket 
(See Figure 4).

NOTE: 

 When installed in the correct orientation, the bottom 

lip of the lifting bracket will be the side closest to the T-track.

7.  Repeat Step 6 for the second lifting bracket at the top section 

of the screen in the opposite corner (See Figure 4).

8.  Position the third lifting bracket 2⅛” from the back of the 

T-track in the center of the top section of the wall opening 
and mount with 1/4”X 1” lag screws (See Figure 4).

NOTE:

 After completing this step, there should be three lifting 

brackets mounted into the top section of the wall opening 
behind the T-track. Check that these brackets are secure. 
They will be used to guide the screen surface into place and 
support its weight until the T-track and screen frame are 
attached to each other.

WARNING: After completing this step, do not proceed 
further in the instructions until the screen surface has 
remained in a flat, unrolled state for at least 4 hours.
