Series 526 Impact Installation Instructions
The 16G3 glass stop has a hook leg that has to go past the frame hook leg towards the
glass. So,it is necessary to push the glass against the preset gasket. This will give the
16G3 leg enough clearance of the frame hook leg. Lift and pull into place. It may be
necessary to use short pieces of the drive-in gasket (W167) to temporarily hold it in place.
For DRY glazing, it is necessary to use SDR1 (10-16 X 3/4 TEK) fasteners to attach the
glass stop, but for a WET glazing, the SDR1 is optional. Predrill the 16G3 glass to locate
the SDR1 6” from each end, and one in the center for anything over 36” a maximum of 24”
on center. Place the short temporary pieces of W167 at fastener locations. This will keep
the 16G3 in place while attaching.
