Section 15 - Exterior Cover Installation
1. Locate and apply vertical covers as shown on the approved Final shop drawings. Engage one side, then use the mallet and block to engage the opposite
side.
2. Center the horizontal snap cover in the opening and apply it in the same manner. Gaps at the ends should be split equally and are to allow for thermal move-
ment and weepage.
Note: Exterior Horizontal covers are cut
D.L.O.—1/16”. The erector must split the
difference on both ends.
Caution:
Care must be taken to avoid damage to the covers
during installation. Use a 12” long 2 x 4 with a mallet or hammer to
seat the covers.
Drill 5/16” diameter weep holes in the
Horizontal Covers at 2” from Daylight
Opening.
