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.
