Securitron UNL-24 UnLatch Strike for Cylindrical Locks, 24VDC

Secure, reliable remote access for cylindrical locksets — engineered for commercial and mission-critical environments. The Securitron by ASSA ABLOY UNL-24 electric strike delivers motorized, motor-driven latch release for cylindrical/tubular locksets while preserving full deadlatch function to maintain door security. Designed for easy retrofit, the UNL-24 fits the standard ANSI 4-7/8" strike cutout and accommodates latchbolts up to 5/8", eliminating the need to alter the jamb and reducing installation time and cost. Built from durable stainless steel and powered by 24V DC, this continuous-duty electric strike supports high-traffic applications and long service life. A standard SPDT latch status sensor provides monitoring and integration with access control, security, and surveillance systems so you can track door state in real time. The UNL-24 also releases under preload for reliable operation on doors under pressure. Ideal for server rooms, retail, healthcare and commercial facilities that require dependable access control with minimal disruption.
