It features a non-removable pin (NRP) for added security, preventing hinge disassembly from the exposed side of the door. Finished in satin chrome, it suits architectural hardware specifications calling for a brushed, low-sheen appearance. The hinge measures 4.5 inches x 4.5 inches and weighs 1.4 pounds, making it appropriate for heavy door assemblies where durability and smooth operation under repeated cycling are required. Installation is performed by licensed door hardware technicians or finish carpenters working to commercial building specifications.\u003c\/p\u003e\n\u003cp\u003eThis hinge is suited for commercial, institutional, and heavy residential door installations where a full-mortise, heavy-weight hinge is specified. Typical applications include high-cycle entry doors, corridor doors, and stairwell doors in commercial buildings. The non-removable pin configuration is commonly specified for doors swinging outward or in any location where hinge-side security is a code or project requirement. The satin chrome finish coordinates with standard commercial architectural hardware finishes across door lever, pull, and lockset selections.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFive-knuckle construction provides increased bearing surface and load distribution across the hinge barrel\u003c\/li\u003e\n  \u003cli\u003eBall bearing operation delivers smooth, low-friction swing suited for heavy door assemblies and high-cycle use\u003c\/li\u003e\n  \u003cli\u003eNon-removable pin (NRP) prevents hinge disassembly from the exterior or unsecured side of the door\u003c\/li\u003e\n  \u003cli\u003eHeavy-weight classification supports larger, heavier commercial door slabs\u003c\/li\u003e\n  \u003cli\u003eSatin chrome finish meets common architectural hardware finish specifications\u003c\/li\u003e\n  \u003cli\u003e4.5 inches x 4.5 inches leaf size fits standard full-mortise commercial door and frame preparations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style full-mortise heavy-weight hinge replacement suitable for commercial doors and frames requiring a 4.5 inches x 4.5 inches five-knuckle ball bearing hinge with a non-removable pin in satin chrome finish.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a qualified door hardware installer or finish carpenter.
