Series 5500 Outside Glazed Installation Instructions

Section VI: Exterior Cover & Drive-In Gasket Installation

STEP #1 INSTALL DRIVE-IN GASKETS IN VERTICAL MULLIONS

A. Remove the exterior drive-in wedge gasket material from the reel, and allow the gasket to

relax and shrink.

B. Remove any temporary retainer gaskets previously applied, from the opening at hand.
C. The exterior vertical gaskets must be cut vertical D.L.O. plus 1 3/4”. Apply the drive-in gas-

kets at the vertical mullions by driving in the wedge gasket, starting at the center of the

D.L.O. Crowd in the excess at the ends. Care should be taken not to stretch the gasket when

installing. The vertical gaskets should run through and extend past the horizontal gaskets,

once the horizontal gaskets are in place.
