Emtek 8121NWUS19 Norwich Knob Passage Set Flat Black

Product Description

The EMTEK 8121NWUS19 is a Norwich knob passage set finished in Flat Black, designed for interior doors where latch function is required without locking. The set includes a rectangular rose and is configured for a 2-3/8 inch backset. It fits doors ranging from 1-1/4 inches to 2 inches in thickness. The Norwich knob profile offers a traditional round form suited to period-style and transitional interiors. Installation is handled by carpenters, finish contractors, or experienced DIYers during new construction or renovation work. The passage function makes this hardware appropriate for hallways, closets, and common areas where privacy hardware is not required.

This passage set is intended for residential interior door applications. The rectangular rose provides a clean, defined wall plate profile that complements both classic and contemporary millwork. The 2-3/8 inch backset is the standard dimension for most residential pre-hung interior doors. Door thickness compatibility ranges from 1-1/4 inches to 2 inches, covering standard hollow-core and solid interior door stock. The Flat Black finish is a matte dark tone suited to modern farmhouse, industrial, and transitional design schemes.

Installation Notes

Installation is typically performed by a finish carpenter or general contractor during interior trim-out. Confirm the door bore diameter and backset measurement before installation to ensure proper latch alignment with the strike plate. No electrical shutoff is required, but all door hardware should be installed before final painting or staining of the door slab. Follow the manufacturer's included template and fastener instructions for proper rose and knob alignment.
