Measuring 4.5 inches in length, this hinge features a US26D satin chrome finish and a 5-knuckle construction with a non-rising pin. It is non-handed, meaning it works on both left- and right-hand applications without modification. The leaf thickness is 0.134 inches, suited for standard door preparations. With 8 mounting holes and a Grade 1 material rating, this hinge is built for commercial and institutional installations. Carpenters, finish contractors, and door hardware specialists are the typical installers.\u003c\/p\u003e\u003cp\u003eThis concealed hinge is appropriate for interior and commercial door installations where exposed hinge hardware is not desired or permitted by design specifications. The non-handed design simplifies ordering and field installation when working on mixed door configurations. The US26D finish coordinates with satin chrome door hardware throughout a building. The 5-knuckle configuration provides added bearing surface compared to standard 3-knuckle hinges, distributing door weight more evenly across the hinge barrel.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4.5-inch length with non-rising pin for smooth, consistent door operation\u003c\/li\u003e\n\u003cli\u003eUS26D satin chrome finish for a clean, low-profile appearance\u003c\/li\u003e\n\u003cli\u003e5-knuckle construction for increased bearing surface and durability\u003c\/li\u003e\n\u003cli\u003eNon-handed design fits left-hand and right-hand door applications\u003c\/li\u003e\n\u003cli\u003e8 mounting holes for secure attachment to door and frame\u003c\/li\u003e\n\u003cli\u003eGrade 1 material rating suitable for commercial-grade installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation concealed hinge for commercial and residential doors requiring a 4.5-inch, US26D-finish, 5-knuckle hinge with standard 8-hole mounting patterns.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by finish carpenters or licensed door hardware technicians. Before installation, ensure the door and frame mortises are properly sized to accept the hinge leaf thickness of 0.134 inches.
