Section V: Glazing Installation
STEP #3 INSTALL ANTI-WALK BLOCKS
A. Stretch the anti-walk blocks until they are elongated enough to fit between the glass face
and the front face of the glazing pocket.
B. Install and position anti-walk blocks in the verticals at the center of each D.L.O. A tool such
as a standard screwdriver may be used to drive the spacer into the glazing pocket far
enough to clear the glass edge, so that it snaps back into shape once it is in the pocket.
