Von Duprin 33A-GBK 33A/35A Glass Bead Kit, Rim Device Prep

Von Duprin 33A-GBK 33A/35A Glass Bead Kit, Rim Device Prep

The Von Duprin 33A-GBK is a heavy-duty architectural hardware adaptation kit designed for mounting Von Duprin 33A and 35A Series narrow-stile rim exit devices onto modern glass-profile doors. When installing panic hardware on aluminum or hollow metal doors with glass lites, protruding glass beads (the metal trim strips holding the glass pane in place) can obstruct the flush placement of the exit device chassis.

The 33A-GBK Glass Bead Kit provides a specialized shim and spacing solution that safely elevates the device mechanism case above the glass bead line. This prevents structural interference with the glazing trim while preserving total structural door integrity. By offering precise physical clearance for the rim device prep, this commercial-grade accessory avoids time-consuming field notches, ensuring a perfectly aligned latch engagement and a clean, professional aesthetic on high-use exterior or interior glazed doors.

Key Features

• Glass Bead Clearance: Specially engineered to shim and lift narrow-stile pushpad devices over raised door glazing beads, eliminating the need to cut or alter the door’s glass trim.

• Narrow Stile Synergy: Precision-contoured to match the slim chassis footprint of the Von Duprin 33A and 35A Series rim exit devices.

• Rim Device Optimization: Formulated explicitly for standard rim device preps, providing stable cross-chassis leveling for smooth panic bar deployment.

• Heavy-Duty Construction: Fabricated from rugged, architectural-grade materials built to absorb continuous physical impacts and maintain device alignment over time.

• Preserved Code Compliance: Facilitates proper field positioning of life-safety hardware on glass-heavy storefronts without violating fire or glazing safety standards.
