Built from heavy-gauge cold-rolled steel, this hinge delivers reliable strength in high-cycle applications. It measures 4 inches in length with 5\/8 inch radius round corners, giving it a clean, finished profile that sits flush with the door and frame. The five-knuckle construction distributes load evenly across the barrel. A flush pin delivers a refined appearance on finished doors. This package contains 15 hinges, making it practical for multi-door projects or service stock.\u003c\/p\u003e\u003cp\u003eThis hinge is suited for standard residential interior and exterior door installations where a mortise-style hinge is required. The countersunk screw holes allow fasteners to sit flush with the hinge leaf, preventing interference with door swing and ensuring a tight fit against the door edge and frame. The removable pin simplifies door hanging and removal, a practical feature for finish carpenters, door installers, and general contractors working on new construction or renovation projects.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHeavy-gauge cold-rolled steel construction for added strength and durability\u003c\/li\u003e\n\u003cli\u003eFive-knuckle, full mortise design for even load distribution\u003c\/li\u003e\n\u003cli\u003e5\/8 inch radius round corners for a clean, finished appearance\u003c\/li\u003e\n\u003cli\u003eFlush pin for a refined look on finished door installations\u003c\/li\u003e\n\u003cli\u003eCountersunk screw holes allow fasteners to sit flush with the hinge leaf\u003c\/li\u003e\n\u003cli\u003eRemovable pin for easier door hanging and removal during installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation hinge for standard residential and light commercial full mortise door applications requiring a 4 inch hinge with 5\/8 inch radius corners.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by carpenters, door installers, or general contractors using a chisel and drill to cut the mortise pocket in the door edge and frame jamb.
