Emtek 5100EUS15 Egg Knob Keyed Entry Satin Nickel

Product Description

The EMTEK 5100EUS15 is an Egg Knob keyed entry lockset finished in Satin Nickel, designed for residential and light-commercial door hardware applications. The knob ships with support for both 2-3/8 inches and 2-3/4 inches backsets, making it compatible with the most common door prep configurations in new construction and replacement installs. The Regular Rose mounting hardware is included. The assembly fits doors ranging from 1-3/8 inches to 2-1/16 inches in thickness. Licensed locksmiths, carpenters, and general contractors install this type of hardware as part of entry door finish-out work.

This keyed entry knob is suited for exterior-facing or interior secured doors in residential settings where a keyed lockset is required. The Egg Knob profile offers a rounded, transitional silhouette that works across traditional and contemporary interior design schemes. With dual backset compatibility, a single unit covers the two standard rough-bore situations encountered in residential framing, reducing the need for job-specific SKU selection. The Satin Nickel finish is a widely specified option that coordinates with brushed metal fixtures and hardware throughout a space.

Adjust the latch backset to the correct setting before mounting the rose and knob assembly. Follow local building codes for keyed entry hardware on egress doors.
