Product Description

The EMTEK 5122HLOUS15LH.RLS is a left-hand keyed entry lever set built around the Helios lever design, finished in Satin Nickel. It ships with a radius latch strike and accommodates both 2-3/8 inch and 2-3/4 inch backsets, making it compatible with the most common residential door prep standards. The square rose provides a clean, geometric mounting profile. Door thickness range is 1-3/8 inches to 2-1/16 inches. This hardware is intended for exterior or interior keyed entry applications and is custom assembled to order. Locksmiths, finish carpenters, and general contractors are the primary installers.

This lever set is suited for residential entry doors where a keyed lockset with a defined left-hand swing orientation is required. The Satin Nickel finish coordinates with a wide range of architectural hardware and fixture lines. The included radius latch strike fits standard door jamb preparations. The square rose mounting style is appropriate for both new construction and retrofit applications where the existing door has a standard bore pattern. No additional trim or rosette is required for a complete installation.
