Emtek 5109ROUUS15 Round Knob Passage Set Satin Nickel

Product Description

The EMTEK 5109ROUUS15 is a round knob passage set in a Satin Nickel finish, designed for interior doors that require passage-only function — no locking mechanism. It pairs a round knob with a disk rose and is configured for a 2-3/8 inch backset. The set accommodates door thicknesses ranging from 1-1/4 inches to 2 inches, making it suitable for standard residential interior door stock. Installation is straightforward for a finish carpenter, locksmith, or experienced DIYer. The Satin Nickel finish provides a clean, low-sheen appearance that coordinates with a wide range of interior hardware.

This passage set is intended for interior doors where latching without locking is required — hallways, closets, living spaces, and similar applications. The disk rose provides a low-profile trim profile around the knob base. The 2-3/8 inch backset is the standard measurement for most pre-bored interior doors in residential construction. Door thickness compatibility of 1-1/4 inches to 2 inches covers the majority of standard hollow-core and solid-core interior doors.

Installation Notes

Installation is typically performed by a finish carpenter or locksmith. Verify the door is pre-bored to the correct backset measurement and cross-bore diameter before installation. Ensure the door thickness falls within the 1-1/4 inch to 2 inch specified range before mounting the through-bolt spindle assembly. Do not force the knob assembly if the latch cartridge does not seat freely — check bore alignment first.
