Product Description

The EMTEK 5122HLOUS4RH.RLS is a right-hand keyed entry lever set in a Satin Brass finish, built around the Helios lever design. It ships with a radius latch strike and supports both 2-3/8 inch and 2-3/4 inch backset configurations, making it adaptable to a wide range of standard door preparations. The lever mounts on a square rose and fits doors ranging from 1-3/8 inches to 2-1/16 inches thick. Each unit is custom assembled to order and sold individually.
