Von Duprin 971573 Lift Spring 992 994 Exit Devices

Product Description

The VON DUPRIN 971573 is a replacement lift spring designed for use in 992 and 994 series exit devices. This small but critical component maintains proper latch retraction and lever or trim return function within the exit device mechanism. When a lift spring fails, the exit device may not operate smoothly or reset correctly after activation, creating a potential life-safety concern. Installation is typically performed by a licensed locksmith or door hardware technician during routine exit device maintenance or as part of a repair call. The part ships as a single unit and measures 1.75 inches in length with a 0.45-inch profile.

This lift spring is intended for commercial door hardware applications where 992 or 994 series Von Duprin exit devices are installed. These exit devices are common in public and commercial buildings including schools, healthcare facilities, office buildings, and retail environments. The 971573 is a direct service replacement sourced to restore original mechanical function to the exit device assembly without requiring full device replacement.
