Installation (continued)
4. While the screen is resting, the T-tracks (B) 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 (B) piece
(See Figure 1). Using one of the 4" pieces of trim (C), snap the
trim into place on one end of the T-track (B), 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 (B) 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 (B) each for the top and bottom
openings.
WARNING: Ensure each #10 countersunk screw head is
inserted completely and does not extend into the T-track
channel. If the screws are not inserted completely, the
screen tensioning assemblies will not slide through the
channel.
