Emtek 8121NWUS3 Norwich Knob Passage Set Polished Brass

Product Description

The EMTEK 8121NWUS3 is a Norwich knob passage set designed for interior doors where a latch mechanism is required but no locking function is needed. It ships with a 2-3/8 inch backset and mounts on a rectangular rose. The Polished Brass Lifetime finish is applied over solid brass hardware. The set suits doors ranging from 1-1/4 inches to 2 inches in thickness. Custom assembly allows the knob, rose, and finish to be selected independently, making this a common specification choice for residential interior finish work and light commercial applications.

This passage set is intended for interior doors such as hallway, closet, and common-room doors that require a latch but no keyed or privacy function. The rectangular rose provides a clean, traditional profile that works with both classic and transitional interior design themes. The 2-3/8 inch backset is standard for most interior door prep. Door thickness compatibility of 1-1/4 inches to 2 inches covers the range of standard hollow-core and solid interior doors found in residential construction.

Installation Notes

Installation is typically performed by a finish carpenter or door hardware installer. Power down any associated door alarm or access-control circuits before beginning work. Confirm door bore diameter and backset measurement before installing to ensure proper latch alignment with the strike plate. Follow the manufacturer-supplied template for rose and latch placement to avoid misalignment.
