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.
