Product Description

The EMTEK 5123HLOUS4LH.RLS is a left-hand keyed entry lever lockset featuring the Helios lever design paired with a Modern Rectangular Rose in a Satin Brass finish. This unit ships with a radius latch strike and accommodates both 2-3/8 inch and 2-3/4 inch backset configurations, making it suitable for a wide range of residential door preps. It is designed for doors ranging from 1-3/8 inches to 2-1/16 inches in thickness. Locksmiths, finish carpenters, and general contractors install this hardware as part of interior or entry door finishing work where keyed security and a defined aesthetic are both required.

This lever set is intended for keyed entry applications on residential exterior or interior passage doors. The left-hand configuration is suited for doors where the hinge is on the right as you face the exterior side. The Helios lever and Modern Rectangular Rose combination is typically selected for transitional or contemporary design schemes. The included radius latch strike is compatible with standard door frame mortise cutouts. Assembly is performed to order at the manufacturer's Southern California facility.

Installation Notes

Installation should be performed by a licensed locksmith, finish carpenter, or qualified contractor familiar with door hardware prep standards. Power tools are not required but a chisel and drill with a hole saw are typical for new door prep. Verify door hand orientation before ordering, as left-hand and right-hand configurations are not interchangeable. Follow local building codes for any keyed entry hardware on egress doors.
