Series 526 Impact Installation Instructions
SECTION IV: Frame Assembly
A. Preset Gasket Installation for Dry Glazed and Wet Glazed
After all the material is cut to the appropriate length, the preset gasket should be
installed. Begin the installation of the preset gasket by first ensuring that the gasket
race is clean and free of debris. The preset gasket should be cut longer than the
frame member it is being installed into. Lay the preset gasket down the length the
frame member. Ensure that the gasket will hang over both ends of the frame
member because once the gasket is snapped-in place, it may be difficult to slide it in
the race. After the gasket is installed, crowd the gasket in from each end as much
as possible, and cut flush with the frame member.
