Measuring 3.5 x 3.5 inches with a 0.25 inch leaf thickness and radius corners, this hinge is built for smooth, quiet operation in demanding door installations. The ball bearing knuckle reduces friction and wear over the life of the door, making it well-suited for frequently used doors in commercial and residential settings. Licensed hardware professionals and finish carpenters install this hinge as part of specified door hardware packages where both function and finish consistency are required.\u003c\/p\u003e\n\u003cp\u003eThis hinge is appropriate for interior and exterior door applications where an architectural-grade, solid brass hinge is called for. The Bright Brass finish coordinates with matching door hardware in residential entryways, office suites, hotel corridors, and institutional buildings. It is sold as a pair, allowing direct procurement for a standard single-door installation. The radius corner profile is the standard configuration for most pre-mortised door frames and factory-bored door blanks in commercial door hardware specifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBall bearing knuckle provides low-friction, long-service operation on high-cycle doors\u003c\/li\u003e\n  \u003cli\u003eSolid brass construction with Bright Brass finish for corrosion resistance and finish consistency\u003c\/li\u003e\n  \u003cli\u003e3.5 x 3.5 inch leaf dimensions with 0.25 inch leaf thickness for standard door specifications\u003c\/li\u003e\n  \u003cli\u003eRadius corner geometry matches common pre-mortised door frames and slabs\u003c\/li\u003e\n  \u003cli\u003eSold as a pair to match standard single-door hardware sets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an architectural-grade replacement or new-installation hinge for standard 3.5 x 3.5 inch full-mortise hinge applications on residential and light commercial doors.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed finish carpenter, door hardware installer, or general contractor.
