Installation (continued)

7. Mount the first lifting bracket (D) in the top section of the wall

opening behind the T-track (B). Measure 2⅛" from the back

(projector side) of the T-track (B) to the back edge of the

lifting bracket (D) 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: Lifting brackets (D) must be parallel to T-track. When

installed in the correct orientation, the bottom lip of the lifting

bracket (D) will be the side closest to the T-track (B).

8. Repeat for the second lifting bracket (D) at the top section of

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

9. Position the third lifting bracket (D) 2⅛" from the back of the

T-track (B) 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 (D) mounted into the top section of the wall opening

behind the T-track (B). 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 (B) 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.
