It ships with a 2-3\/8 inch backset and mounts on a rectangular rose. The Polished Brass Lifetime finish is applied over solid brass hardware. The set suits doors ranging from 1-1\/4 inches to 2 inches in thickness. Custom assembly allows the knob, rose, and finish to be selected independently, making this a common specification choice for residential interior finish work and light commercial applications.\u003c\/p\u003e\n\u003cp\u003eThis passage set is intended for interior doors such as hallway, closet, and common-room doors that require a latch but no keyed or privacy function. The rectangular rose provides a clean, traditional profile that works with both classic and transitional interior design themes. The 2-3\/8 inch backset is standard for most interior door prep. Door thickness compatibility of 1-1\/4 inches to 2 inches covers the range of standard hollow-core and solid interior doors found in residential construction.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePassage function: latch only, no locking or privacy mechanism\u003c\/li\u003e\n  \u003cli\u003e2-3\/8 inch backset fits standard interior door bore prep\u003c\/li\u003e\n  \u003cli\u003eCompatible with door thicknesses from 1-1\/4 inches to 2 inches\u003c\/li\u003e\n  \u003cli\u003eRectangular rose profile for a traditional or transitional aesthetic\u003c\/li\u003e\n  \u003cli\u003ePolished Brass Lifetime finish for long-term appearance retention\u003c\/li\u003e\n  \u003cli\u003eSold as a single set (EA); case quantity of 12 available for project orders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style passage set for interior residential and light commercial doors with a standard 2-3\/8 inch backset and a door thickness between 1-1\/4 inches and 2 inches.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a finish carpenter or door hardware installer.
