Part of the V125 series, this 3-inch hinge is constructed from cold-rolled steel with a solid brass adjustable collar. The fully enclosed spring mechanism provides consistent closing force, and the stud pin allows the installer to dial in the desired closing speed. No mortising is required, making this a straightforward surface-mount installation. Sold as a 2-pack with mounting screws included.\u003c\/p\u003e\n\u003cp\u003eThis hinge is suited for residential and light commercial door installations where a self-closing mechanism is needed without the complexity of a mortised hinge. The full-surface design mounts directly to the face of the door and frame, reducing installation time. It accommodates both right-hand and left-hand door swings, making it a flexible option across a range of door configurations. Typical applications include utility rooms, storage areas, mechanical rooms, and other interior doors requiring code-compliant self-closing hardware.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFull-surface mount design eliminates mortising for faster installation\u003c\/li\u003e\n  \u003cli\u003eCompatible with right-hand and left-hand door swings\u003c\/li\u003e\n  \u003cli\u003eSolid brass adjustable collar with stud pin for closing speed control\u003c\/li\u003e\n  \u003cli\u003eFully enclosed spring for durability and consistent closing force\u003c\/li\u003e\n  \u003cli\u003eIncludes mounting screws — ready to install out of the package\u003c\/li\u003e\n  \u003cli\u003eSold as a pair (2-pack) per package\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a full-surface replacement or new-installation spring hinge for standard interior doors in residential and light commercial settings.
