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.\u003c\/p\u003e\n\u003cp\u003eThis 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.
