Designed for use in applications where durability is the deciding factor, the RCI 3800 Series lever set has a unique "clutch" mechanism that radically reduces wear and abuse experienced with typical cylindrical lever sets. When locked, the lever disengages from the retractor and other interior mechanisms of the lock. The lever swings freely without resistance, reducing wear on lock components and eliminating "lever droop." RCI's 3800 Series Grade 1 Electrified Cylindrical Lock Set is an ideal solution for high traffic commercial applications. Information: www.rutherfordcontrols.com.
