Note: On some custom sized frames, the use of additional “back support braces” is required. 
These vertical support braces assure parallel top and bottom frame member alignment once the 
screen has been attached to the frame. Do not install the screen/frame without required back 
braces. See Image A.

Back Braces Installation Tips:

1. Install the four sections of the main frame. 
2. Partially install the screen material onto the frame. Snap or hook the screen material on the bottom 
and sides leaving the top loose. 
3. Install the back braces and measure to make sure the frame is still square. 
4. Finish installing the top of the screen material.
