National Marker N114975 Spring Door Hinge 3 in Black 2-pack

Product Description

The NATIONAL MARKER N114975 is a full-surface spring door hinge designed for interior door applications where controlled, automatic closing is required. 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.

This 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.

Installation Notes

Installation is typically performed by a finish carpenter, general contractor, or qualified maintenance technician using standard hand tools. Power down or secure the door before beginning to prevent movement during installation. Mount to the door face and frame face with the included screws, then use the stud pin to adjust closing speed before final tightening of the collar. Follow applicable local building codes for self-closing door hardware requirements.
