Installation (continued)

3.  While the screen is resting, the T-tracks can be installed into 

the wall opening. Measure 2½” from the side of your wall 
opening to locate the end of the first T-track piece  
(See Figure 1). Using one of the 4” pieces of trim, snap the 
trim into place on one end of the T-track, place the T-track in 
the opening and slide until the lower portion of the trim is 
against the wall. Secure that end of the track with a #10 screw 
in the hole closest to the end (See Figure 2).

NOTE:

 Most screen units will have one piece of T-track for the 

side openings and two pieces each for the top and bottom 
wall openings. Larger sized units (above 14’ wide) may have 
three pieces of T-track each for the top and bottom openings.

4.  Using the other 4” piece of trim as a guide, secure the 

opposite end of the T-track section on the end hole with a #10 
screw. Once both ends are attached, slide the 4” trim pieces 
along the track to align the other positions and attach a #10 
screw into the hole openings until completed (See Figure 2).

 NOTE:

 Sliding the trim along the T-track will maintain the 

proper alignment when attaching the T-track to the wall.  This 
alignment is necessary to allow the trim to snap on easily at 
the end of the screen installation. Ensure the opening is level 
on all four sides. If the opening is not level, the T-track will 
need to be shimmed in order to ensure the screen trim is 
level once attached to the T-track. 

5.  Repeat Steps 3 and 4 until all T-track sections have been 

secured to the wall opening (See Figure 3). For top and 
bottom sections, use 4” piece of trim to overlap at the seams 
as a guide to ensure that both T-track pieces are flush with 
each other in the wall opening.
