Verify that the U-channel [3] is cut
properly using the below formulas:
U-channel Height = Unit Height - 2 3/4”
or
U-channel Height = Panel Glass Height - 9/16“
Note: If out of level conditions exist be sure
to use the longer U-channel on the appropriate
side (see illustration).
Next, drill three 3/16” diameter holes in the
center of U-channel (centerline groove
provided for convenience); one hole 2-1/2”
from each end and one hole in the middle.
Place the U-channel over the wall centerline
marked in step one. With a pencil, carefully
mark each hole position on the wall centerline.
Drill a 3/16” diameter hole, approximately 1”
deep, directly on the wall centerline at the
marked locations.

Insert a wall plug [16] into each drilled
hole. Then carefully cut the heads off of the wall plugs
[16] with a razor blade. So there is nothing
raised above the surface of the wall.
Place the u-channel [3] in position and secure
it with #8 x 1-1/2” truss head screws [18].
Note: Do not overtighten the screws.
