Marks Hardware 175AB10B-3/4 Entry Clutched Lever Lockset is an exceptional choice for those seeking durability and reliability in a cylindrical lock. Crafted with a Marks C keyway and a robust 6-pin cylinder, this Grade 2 lockset is designed to withstand the test of time, featuring a backset of 2-3/4 inches and an ANSI strike for seamless integration into your residential or commercial space. What sets this lockset apart is its innovative "clutch" mechanism, which significantly reduces wear and tear on the internal components. When locked, the levers disengage, allowing them to move freely without resistance, thereby preventing lever droop and extending the lock's lifespan. The solid cast Zamac levers and stainless steel nose ensure robust performance, while the 3-hour fire rating adds an essential layer of safety. Additional features include a high-quality design that exceeds BHMA grade 1 specifications by 300%, offering over 3.6 million cycles of use. The lockset is also compatible with doors ranging from 1-5/8 inches to 1-7/8 inches in thickness. With a sleek dark bronze finish (613/US10B) and a lifetime mechanical warranty, the Marks Hardware 175AB10B-3/4 Entry Clutched Lever Lockset is the ideal solution for those who demand both style and security.

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 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.
