The assembly is custom-configured and suited for exterior or interior keyed entry applications where a consistent, cohesive hardware finish is required. At 4.25 pounds, the set is built for lasting use in residential door installations handled by finish carpenters, locksmiths, and general contractors.

This lever set is designed for doors ranging from 1-3/8 inches to 2-1/16 inches in thickness, covering the majority of standard residential interior and exterior door slabs.
