Marks USA 175 Series Grade 2 Cylindrical Lever Locksets

Marks USA Cylindrical Locksets are designed for use in situations where durability is the deciding factor. Our cylindrical lock chassis are all constructed with cast retractors on bronze roller bearings. This strong, durable component gives our cylindrical sets the ability to last millions of cycles and is available in knob and lever sets.

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.
