Emtek 5112ROUUS3NL Round Knob Passage Set Unlacquered Brass

Product Description

The EMTEK 5112ROUUS3NL is a passage knob set configured for doors that do not require locking, such as hallway and closet applications. It pairs a round knob with a modern rectangular rose plate and is factory-set for a 2-3/8 inch backset. The set is finished in unlacquered brass, which develops a natural patina over time rather than maintaining a sealed, consistent sheen. Suitable for doors ranging from 1-1/4 inches to 2 inches in thickness, this hardware is designed to meet both functional and aesthetic requirements in residential interior door installations. A licensed carpenter, finish carpenter, or experienced installer typically handles the fitting.

This passage set is intended for interior doors where privacy or security hardware is not required. Common applications include hallways, living rooms, dining rooms, and closet doors in residential construction or renovation projects. The modern rectangular rose provides a clean, linear profile that complements contemporary and transitional interior design schemes. The unlacquered brass finish is well suited for spaces where a living finish is preferred, allowing the metal to age naturally with use and exposure.
