Marks USA 195 Grade 1 Series is hands down the BEST performing Grade 1 Lever on the market. Named the "Survivor Series" way back in the day, the 195 was the only thing that could withstand constant abuse. Perfect for commercial applications in Office Buildings, Schools, Universities, Hospitals and more. UL Listed for 3-hour fire rating, and satisfy ADA requirements. ANSI-A156.2, BHMA Certified.
The Marks USA Survivor leverset has a unique "clutch" mechanism that radically reduces the wear and abuse that typical cylindrical lever sets endure. When locked, the levers of the Survivor disengage from the retractor and other interior mechanisms of the lock. The levers of the Survivor swing freely, without resistance. This reduces the amount of wear on lock components and eliminates "lever droop". The use on a clutch results in longer lasting, lower maintenance, eloquent solution.
MARKS USA LOCDOWN™ CLASSROOM INTRUDER LOCKSETS
To answer the challenge of security and life safety in today’s classroom environment, MARKS USA Custom Lockset Division has developed the LocDown™ Classroom Intruder ANSI/BHMA F110 Function Leverset with Clutch Design (MARKS USA Function DB). MARKS USA has incorporated all of the standard features of their Survivor Series Locksets (Clutch System, Super Strength Retractor, Long Life Lever Support Springs and a Life Test of over 3 Million Cycles) with their new Life Safety Classroom Intruder Function.
At the first sign of trouble outside; lock down a classroom instantly with MARKS USA’s LocDown™ Classroom Intruder Locksets. Classroom function cylindrical (F110 function) and mortise (LA318GJ) locksets are designed to be locked or unlocked from the exterior with the interior always in an open position, but allows in emergency life safety situations the teacher to secure the classroom without stepping into the hallway to lock the outside handle. Faculty & students remain safely within the classroom. There is no need to open the door, the exterior lever is disabled by operating the interior lock cylinder.
