National Marker N115006 Spring Door Hinge 3 in 2-pack

Product Description

The NATIONAL MARKER N115006 is a full-surface spring door hinge designed for residential and light commercial door installations. Part of the V125 series, this 3-inch hinge is constructed from cold-rolled steel with a solid brass adjustable collar and a fully enclosed spring mechanism. The stud pin allows the installer to dial in the desired door closing speed without removing the hinge. Because it uses a full-surface mount, no mortising or chiseling is required, making installation straightforward for carpenters, handymen, and general contractors. Each pack includes one pair of hinges with mounting screws.

This hinge works on both right-hand and left-hand doors, making it a versatile option for interior and light-duty exterior door applications. The V125 series full-surface design is well suited for retrofit installations where door frames or door edges cannot be easily mortised, or where a faster installation is preferred. The adjustable closing speed makes it appropriate for high-traffic doorways that require controlled, automatic closure. Sold as a 2-pack with screws included.

Compatibility

Designed as a full-surface spring hinge replacement for standard interior and light-duty doors; fits both right-hand and left-hand door configurations per the V125 series specification.

Installation Notes

Installation requires only basic hand tools and no mortising of the door or frame. Power down any adjacent electronic door hardware before working on the door assembly. Adjust the stud pin to set closing speed after the hinge is fully mounted and screws are tightened. Consult applicable local building codes for door hardware requirements in commercial or accessibility applications.
