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.
