Marks USA 175T Corridor Lever Lockset - Grade 2 Survivor Series, American Lever, Cooridor
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 of a clutch results in longer lasting, lower maintenance, eloquent solution.
