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.\u003c\/p\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDirect replacement lift spring for 992 and 994 series exit devices\u003c\/li\u003e\n  \u003cli\u003eCompact profile at 1.75 inches long and 0.45 inches in cross-section\u003c\/li\u003e\n  \u003cli\u003eSingle-unit packaging suitable for field repair and service calls\u003c\/li\u003e\n  \u003cli\u003eRestores proper latch retraction and trim return function\u003c\/li\u003e\n  \u003cli\u003eLightweight component at 0.01 pounds for easy handling and carry stock\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement lift spring for Von Duprin 992 and 994 series exit devices.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed locksmith or qualified door hardware technician.
