Emtek 5123HLOUS19LH Helios Lever Keyed Entry Left Hand

Product Description

The EMTEK 5123HLOUS19LH is a left-hand keyed entry lever set featuring the Helios lever style paired with a Modern Rectangular Rose in a Flat Black finish. This unit is designed for exterior or interior doors requiring a keyed lockset and accommodates both 2-3/8 inch and 2-3/4 inch backsets, making it compatible with standard residential and light commercial door prep. The assembly fits doors ranging from 1-3/8 inches to 2-1/16 inches in thickness. The Flat Black finish delivers a clean, contemporary look suited to modern architectural hardware applications. Installation is handled by a licensed carpenter, general contractor, or experienced finish trim professional.

This lever set is appropriate for residential entry doors, interior locking doors, and light commercial applications where a keyed entry function is required. The left-hand designation specifies handing for the door swing and latch orientation. The Modern Rectangular Rose provides a geometric, low-profile escutcheon that complements contemporary and transitional door styles. The dual backset compatibility eliminates the need for a separate strike plate relocation on most standard door preps.

Installation Notes

Install this lever set with the door removed from service or held open and the latch fully retracted to prevent accidental engagement during fitting. Verify door handing before installation, as this unit is designated left-hand and is not field-reversible without the correct handed components. A standard door hardware installation kit including a Phillips screwdriver and a tape measure is typically sufficient for the mechanical installation. Confirm backset measurement from the edge of the door to the center of the bore hole before final mounting.
