Emtek 5122ROUUS15.RLS Round Knob Keyed Entry Satin Nickel

Product Description

The EMTEK 5122ROUUS15.RLS is a keyed entry knob set finished in Satin Nickel, designed for residential and light-commercial door hardware applications. It accommodates both 2-3/8 inch and 2-3/4 inch backsets, making it compatible with standard door prep found across most residential construction. The set includes a radius latch strike and mounts on a square rose. It fits doors ranging from 1-3/8 inches to 2-1/16 inches in thickness. Installation is handled by finish carpenters, general contractors, or experienced DIYers performing door hardware replacement or new construction finish work.

This keyed entry set is suited for exterior or interior locking doors in residential settings — front entries, side doors, and any passage requiring key-operated locking from the exterior side. The round knob profile pairs with a square rose for a transitional aesthetic that works across a range of architectural styles. The Satin Nickel finish provides a brushed, low-reflectance surface that resists visible fingerprints and integrates with common fixture finishes found in modern and traditional interiors.

Installation Notes

Installation is typically performed by a finish carpenter or qualified door hardware installer. Before installation, confirm the door bore diameter and backset measurement match the hardware set. Ensure the door is not under power or connected to any access control circuit before disassembling existing hardware. Follow local building codes for keyed egress requirements on doors used as a means of egress.
