In 1908 Von Duprin invented the first panic exit device and immediately became the market leader in life saving exit device. Today, innovation, durability, and our never-ending dedication to saving lives continues to be the driving force behind everything we do. Never has this been more apparent than in the new 33A/35A exit device series. Over thirty years ago, Von Duprin introduced the first pushpad exit device, the 33 Series. This exit device set the standard for future innovations in performance and function. Today, Von Duprin continues in this long tradition with the introduction of the 33A/35A device. This narrow stile exit device comes to the marketplace with advanced features and benefits such as:

• Deadlocking latchbolt on the Rim. Surface Vertical and Concealed Vertical functions. The deadlocking feature will provide unparalleled security and performance and will be provided as a standard device feature.
• A one-piece center case cover, which provides a sleek appearance with a consistent aesthetic finish.
• Simplified concealed vertical rod adjustment. Procedure now improved to duplicate the 99 concealed vertical rod process. This saves time required for normal maintenance…and time is money.
• Shearpin construction incorporated in lever and thumbturn trim. Provides simplified and low cost servicing procedure.
• Rotary input cam construction similar to the 98/99 device series. Same durability and performance value found in the Von Duprin core device line.
• Molycoated latchbolt on Rim, Surface Vertical, and Concealed Vertical models. Coating provides long term lubrication and superior durability to device latchbolt.

These design upgrades are just of few of the improvements incorporated into this device series. The versatility and improved mechanical performance of this exit device series establishes another benchmark for the Von Duprin Division of Ingersoll Rand.
