National Mfg N114-975 Adjustable Spring Hinge Black 2 Pack

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N114-975 is a heavy-duty adjustable spring hinge designed to provide controlled, self-closing action across a variety of door applications. Manufactured from cold rolled steel with a black finish, this full surface hinge installs directly onto the door and frame face with no mortising required. The adjustable collar allows the installer to dial in the desired closing speed, making it suitable for light commercial and residential doors where consistent, automatic closure is needed. Each package contains two hinges weighing 1.85 pounds combined.

This hinge is suited for full surface applications on interior doors, screen doors, gate doors, and similar swinging door assemblies where self-closing function is required. The tight pin design accommodates either right-hand or left-hand door swing without modification, eliminating the need to stock separate handed units. The adjustable spring tension makes it adaptable to doors of varying weights and closing speed requirements. Installers in residential and light commercial settings will find this a practical, tool-friendly option for high-use entry points.

Installation Notes

Installation is performed with standard hand tools — no mortising equipment needed. Ensure the door is properly supported and the frame is plumb and square before mounting. Adjust the collar incrementally to achieve the desired closing speed, and verify the door closes and latches fully without slamming. Follow applicable local building codes for self-closing door requirements in commercial or fire-rated door assemblies.
