The set includes a rectangular rose and is configured for a 2-3\/8 inch backset, fitting doors ranging from 1-1\/4 inches to 2 inches in thickness. The Norwich knob features a traditional profile suited to classic and transitional interior design schemes. Installation is handled by carpenters, finish contractors, or experienced DIYers during new construction or renovation work. The oil rubbed bronze finish provides a dark, mildly textured surface appearance consistent with period and transitional hardware aesthetics.\u003c\/p\u003e\n\u003cp\u003eThis passage set is intended for interior doors such as hallway doors, closet doors, and room entries where a latch function is needed but no privacy or keyed lock is required. The rectangular rose provides a clean, defined wall-plate appearance at the door face. The 2-3\/8 inch backset is the standard dimension for most residential interior door prep, and the door thickness range of 1-1\/4 inches to 2 inches covers standard residential hollow-core and solid-core interior slabs. Each unit is sold individually.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePassage function — latch only, no locking mechanism\u003c\/li\u003e\n  \u003cli\u003e2-3\/8 inch backset for standard residential interior door prep\u003c\/li\u003e\n  \u003cli\u003eCompatible with door thickness from 1-1\/4 inches to 2 inches\u003c\/li\u003e\n  \u003cli\u003eRectangular rose included\u003c\/li\u003e\n  \u003cli\u003eOil Rubbed Bronze finish with traditional dark patina appearance\u003c\/li\u003e\n  \u003cli\u003eNorwich knob profile suited to classic and transitional interiors\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a passage-function replacement or new-installation knob set for residential interior doors with a standard 2-3\/8 inch backset and a thickness between 1-1\/4 inches and 2 inches, paired with a rectangular rose mounting plate.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by finish carpenters or qualified contractors following standard door hardware procedures.
