GD310-1224 UL Listed Electric Strike – No Frame Cutting, 12/24VDC, 1000 lbs, Fail-Safe/Fail-Secure, ANSI Grade for Cylindrical Locks

The GD310-1224 is an ANSI-sized electric strike designed for cylindrical or mortise latch sets (without deadbolt) in hollow-metal or aluminum frames. It offers dual-voltage flexibility (12 VDC / 24 VDC) and field-selectable fail-safe or fail-secure operation, making it versatile for varied access-control installations. With a brushed stainless-steel (US32D) face-plate and zinc-alloy body, it combines durability and retrofit compatibility for commercial door applications.
