Von Duprin 33A-GBK Glass Bead Kit for 33A and 35A Series Narrow Stile Rim Exit Devices

Precision Shim and Spacing Solution for Glazed Door Rim Device Installations

The Von Duprin 33A-GBK Glass Bead Kit is a heavy-duty architectural hardware adaptation kit engineered specifically for mounting Von Duprin 33A and 35A Series narrow-stile rim exit devices onto modern glass-profile doors. 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 resolves this challenge by providing a specialized shim and spacing solution that safely elevates the device mechanism case above the glass bead line, preserving total structural door integrity while maintaining a clean, professional aesthetic. Rated as an ANSI/BHMA Grade 1 certified accessory, this commercial-grade kit is fabricated from high-impact commercial architectural composition materials built for demanding, high-use environments.

Professional Features & Benefits

  • 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 for a clean, code-compliant installation.
  • Narrow Stile Synergy: Precision-contoured to match the slim chassis footprint of the Von Duprin 33A and 35A Series rim exit devices, ensuring a secure and properly aligned fit without modification.
  • Rim Device Optimization: Formulated explicitly for standard rim device preps, providing stable cross-chassis leveling for smooth panic bar deployment and reliable latch engagement.
  • Heavy-Duty Construction: Fabricated from high-impact commercial architectural composition materials built to absorb continuous physical impacts and maintain device alignment over time in high-traffic applications.
  • Preserved Code Compliance: Facilitates proper field positioning of life-safety hardware on glass-heavy storefronts without violating fire or glazing safety standards, supporting ANSI/BHMA Grade 1 certification requirements.
  • Kit Components: Includes profile-matched chassis shims and elongated mounting hardware for a complete, ready-to-install solution.
  • No Field Notching Required: Provides precise physical clearance for the rim device prep, avoiding time-consuming field notches and ensuring a perfectly aligned latch engagement on glazed doors.

Von Duprin 33A-GBK-R-SP28 – Frequently Asked Questions

1) Will a Von Duprin 33A or 35A rim exit device mount on a glass door where the glazing bead sticks out past the stile?
That is exactly what the 33A-GBK Glass Bead Kit is for. On aluminum or hollow metal doors with a glass lite, the metal bead holding the pane can sit proud of the stile face and stop the device chassis from sitting flat. The kit shims the 33A or 35A chassis out past the bead line so the device mounts flush and level, with no cutting or notching of the glass trim. It includes the profile-matched chassis shims and the longer mounting hardware the added standoff requires.
2) Which exit device prep do I order the 33A-GBK glass bead kit for?
Three preps are offered, and you pick the one matching the device already going on the door: R for rim device prep, SV for surface vertical rod prep, and CV for concealed vertical rod prep. The prep choice is not cosmetic, it sets the mounting pattern the shim is drilled for, so a rim kit will not line up on a surface vertical rod chassis.
3) Is the Von Duprin 33A-GBK glass bead kit approved for a fire rated door opening?
No. The 33A-GBK carries no fire rating, so keep it off labelled fire door assemblies. It is intended for glazed storefront and aluminum-frame entrances, which are typically non-rated exit openings. For a rated glass opening you need hardware and glazing that are both labelled for it.
4) Will the 33A-GBK fit a Von Duprin 98 or 99 series device, or another brand's narrow stile exit device?
No. The kit is contoured to the narrow-stile chassis footprint of the Von Duprin 33A and 35A Series only, and it mounts without modification because it matches that specific profile. For a wide stile device or a different manufacturer's pushpad, you need the glass bead or filler kit built for that device family.
5) What finishes does the Von Duprin 33A-GBK glass bead kit come in?
Seven finishes, and they are the storefront-matching set: SP28 aluminum painted, SP313 dark bronze anodized aluminum, SP10 satin bronze clear coated, SP4 satin brass, US3 bright brass, US26 bright chrome, and US19 black coated. Match the kit to the device finish, since the shim sits in the open between the chassis and the door face where it is visible. All seven are offered on each of the three device preps.
6) Can I use one glass bead kit for a pair of glass doors with vertical rod devices?
Order one kit per door leaf. The kit shims a single device chassis, so a pair of glazed doors running surface or concealed vertical rod devices takes two, both in the SV or CV prep as applicable. Mixed openings happen too, a rim device on the active leaf and a vertical rod on the inactive, and in that case the two kits are different preps.
7) Does the glass bead kit throw off latch engagement by pushing the exit device off the door face?
It should not, provided the strike is set to the shimmed position. The kit levels the chassis across its full length rather than packing out one end, so the pushpad strokes true and the latch presents square. Since the device now stands proud of the door face by the shim thickness, set the rim strike or the vertical rod top and bottom strikes to the new plane during install.
8) Is the 33A-GBK glass bead kit rated for a high-traffic commercial entrance?
It is a commercial-duty Grade 1 accessory, built from high-impact architectural composition material to hold device alignment under repeated impact. That suits a school, healthcare, retail or municipal entry where the door cycles all day. It is not a residential part.
9) Does the 33A-GBK glass bead kit work with an electrified 33A or 35A device with request-to-exit?
Yes, request-to-exit is the switch function associated with the 33A-GBK. The kit is a mechanical standoff, it does not interrupt the device internals, so an RX-equipped 33A or 35A still reports as normal once shimmed. Allow for the wire run at the hinge or raceway, since the chassis now sits further off the door face.
