Emtek 5122HLOUS19LH Helios Lever Keyed Entry Left Hand

Product Description

The EMTEK 5122HLOUS19LH is a left-hand Helios lever keyed entry set finished in Flat Black, designed for residential and light commercial door hardware applications. The set includes a square rose and accommodates both 2-3/8 inch and 2-3/4 inch backset configurations, making it compatible with standard door preparations. It fits doors ranging from 1-3/8 inches to 2-1/16 inches in thickness. The complete assembly weighs 4.25 pounds and ships as a single unit. This hardware is typically installed by carpenters, general contractors, or experienced finish tradespeople performing door hardware replacement or new construction finish work.

This lever set is suited for exterior or interior keyed entry applications on residential doors. The Flat Black finish works across a range of architectural styles including contemporary, transitional, and modern farmhouse interiors. The square rose provides a clean, geometric backplate profile. The dual backset compatibility — 2-3/8 inches and 2-3/4 inches — allows use on both new and retrofit door installations without requiring a separate chassis. This unit is sold individually and is custom assembled to order.

Compatibility

Designed for left-hand doors ranging from 1-3/8 inches to 2-1/16 inches thick with a standard 2-1/8 inch bore, using either a 2-3/8 inch or 2-3/4 inch backset. No specific model or system compatibility was provided in the product data.

Installation Notes

Installation is performed by a finish carpenter or general contractor using standard door hardware tools including a screwdriver and tape measure. Confirm door handedness before installation — installing a left-hand lever on a right-hand door will result in incorrect lever orientation. Verify the door bore diameter and backset measurement before assembly. Follow the manufacturer's included instruction sheet for latch and rose mounting sequence.
