Emtek C5112ROUUS19 Round Knob Passage Set Flat Black

Product Description

The EMTEK C5112ROUUS19 is a round knob passage set finished in flat black and designed for interior doors where a latch but no lock is required. It ships with a modern rectangular rose and a CF (Clutch Free) mechanism that allows the knob to turn freely from both sides, making it well suited for hallways, closets, and living spaces. The set accommodates a standard 2-3/8 inch backset and fits door thicknesses from 1-3/8 inches to 1-3/4 inches. A licensed contractor, finish carpenter, or experienced installer typically handles the final trim-out on residential projects.

This passage set is intended for residential interior door applications where privacy hardware is not needed. Common install locations include hallway doors, bedroom closets, pantries, and other non-locking passage points. The modern rectangular rose provides a clean, contemporary profile that pairs with transitional and modern interior design themes. The flat black finish coordinates with current fixture and hardware trends across residential construction and renovation work.

Installation Notes

Installation is performed by a finish carpenter, general contractor, or experienced installer. Power down any associated electronic hardware and verify the door prep matches the required backset before beginning. Follow door manufacturer specifications for bore hole diameter and edge bore placement. Do not over-tighten mounting screws, as this can distort the rose or restrict knob rotation.
