Installation (continued)

18. At the top section, align the T-track and the frame. Insert eight

tensioning assemblies (four per frame section for larger

screens). Align the tensioning assemblies so that they are

evenly spaced across the length of T-track and frame (See

Figure 9)

19. Tighten a minimum of two tensioning assemblies per frame

section between the T-track and frame using a 1/2" wrench.

After two or three turns on one tensioning assembly, move to

another in order to prevent the bolts and nuts from binding.

Keep using this alternating method until at least two (or

more) tensioning assemblies, per frame section, have secured

the frame to the T-track on the top section of the screen

assembly. As the tensioning assemblies are tightened the

screen frame will pull gradually closer to the T-track until

there is no more adjustment.

CAUTION: Do not proceed to next steps until a minimum

of two tensioning assemblies per frame section are

attached fully and are holding the screen weight on the

top side.

20. Remove the three lifting brackets from the wall opening

behind the T-track by loosening and removing the 1/4" x 1" lag

screws. The three ropes should also be removed at this time.

NOTE: Once the lifting brackets have been removed, the

screen assembly will be held in place by the previously

attached tensioning assemblies.

21. Tighten the remaining tensioning assemblies on the top

section of the screen assembly until all eight (four per frame

section) are evenly spaced and secure on the top side.

NOTE: Use the alternating method of two to three turns on

one assembly then moving on to another assembly to

prevent the bolts and nuts from binding.

22. At the bottom section, align the T-track and the frame. Insert

eight tensioning assemblies (four per frame section for larger

screens). Align the tensioning assemblies so that they are

evenly spaced across the length of T-track and frame.

23. Begin tightening the tensioning assemblies between the

T-track and frame using a 1/2" wrench. After two or three turns

on one tensioning assembly, move to another in order to

prevent the bolts and nuts from binding. Keep using this

alternating method until the tensioning assemblies have

secured the frame to the T-track.

NOTE: These tensioning assemblies do not need to be

tightened down completely (no threads showing) because

the top frame is already anchoring the screen in place. The

bottom needs to be secure enough to the installer's

discretion.

24. Repeat Steps 22 and 23 for the left and right sides of the

frame, using only four tensioning assemblies per frame

section.

25. Snap the trim into place on the T-track on all four sides of the

finished screen assembly.

26. Carefully remove the protective paper on the audience side

of the screen surface to complete the installation.
