Von Duprin 090040 Hex Dogging Shafts Pack of 2

Product Description

The VON DUPRIN 090040 is a pack of two hex dogging shafts designed for use with Von Duprin exit device hardware. Dogging shafts allow a push-bar exit device to be held in the depressed, latched-back position, enabling free egress through the door without activating the push bar mechanism each time. These shafts are a small but critical component in high-traffic commercial door applications. Each shaft is compact and lightweight, making them straightforward to install during routine exit device service or replacement. The pack of two supports common service scenarios where a spare or a matching pair is needed.

Hex dogging shafts are used in commercial and institutional buildings wherever Von Duprin exit devices are installed. Typical applications include schools, hospitals, office buildings, and other public facilities that require code-compliant emergency egress hardware. Technicians installing or servicing Von Duprin panic hardware will find these shafts to be a direct-fit component for restoring proper dogging function to existing exit devices.

Installation Notes

Installation of dogging shafts is typically performed by a licensed locksmith or door hardware technician familiar with exit device mechanics. Before servicing the exit device, ensure the door is secured in an open position and all building occupants are notified of the temporary egress condition. No power shutoff is required for standard mechanical exit devices, but any electrified dogging or access control integration should be de-energized before work begins. Work must comply with applicable local building and life safety codes governing emergency egress hardware.
