Constructed from steel with a plain finish, this hinge measures 3.5 inches in height and 3.5 inches in width, giving it a nominal size of 3.5 x 3.5 inches. The non-removable pin adds a layer of security by preventing the pin from being driven out when the door is closed. Licensed contractors and commercial door hardware installers specify this type of hinge for heavy-duty swing doors in institutional, commercial, and industrial settings.\u003c\/p\u003e\u003cp\u003eFull surface hinges are commonly used where mortising is not practical or where door and frame materials make cut-in installation difficult. This hinge suits commercial interior doors, metal-clad doors, and retrofit applications where the original mortise hinge has failed and a surface-mount solution is preferred. The extra heavy designation indicates a reinforced leaf thickness appropriate for high-cycle or high-traffic door installations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFull surface mount — no mortising required on door or frame\u003c\/li\u003e\n\u003cli\u003eNon-removable pin for added door security\u003c\/li\u003e\n\u003cli\u003eSteel construction for extra heavy duty service\u003c\/li\u003e\n\u003cli\u003eNominal size 3.5 x 3.5 inches suits standard commercial door applications\u003c\/li\u003e\n\u003cli\u003eLeaf thickness of 0.120 inches provides rigid, durable load bearing\u003c\/li\u003e\n\u003cli\u003ePlain finish accepts field painting or coating after installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style full surface replacement hinge for commercial and institutional doors requiring extra heavy duty hardware with a 3.5 x 3.5 inch nominal size and full surface mounting.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed door hardware technician or commercial contractor.
