Series 526 Impact Installation Instructions
Ensure that the glass, setting blocks, snap-in glazing bead, and anti-walk blocks have
been installed according to the instructions on the previous pages. Begin by measuring
the D.L.O. width and height. Cut the drive-in glazing gasket (W167) to length by using the
following formula.
EXTERIOR GASKET CUT LENGTH = D.L.O. DIM + 2% (D.L.O. DIM X 1.02)
Seal 1” vertically and horizontally in the gasket race with silicone type sealant at all
corners. Seal the ends of the horizontal gaskets to the vertical gaskets. To install the
W167 gasket, start by pushing the precut gasket in place at the ends. Move to the middle,
then to 1/4 points, and work the "waves" toward the ends. Try to maintain 8" to 12" place-
ment of the gasket to ease the installation.
Note: Install the vertical gasket first, then run the horizontal gasket into it.
