Best 711420754 Spring Hinge Full-mortise Satin Brass

Product Description

The BEST 711420754 is a full-mortise spring hinge designed for doors that require automatic self-closing action. Constructed from steel with a satin brass finish, it provides a load capacity of 200 pounds and a door leaf height of 3.5 inches. The spring mechanism stores energy as the door opens and returns it to a closed position without a separate closer device. This hinge is installed by finish carpenters, door hardware specialists, and commercial door technicians in both new construction and retrofit applications where code or facility management requires doors to close automatically.

This hinge is suited for interior doors in commercial and institutional settings where self-closing hardware is required. The full-mortise mount type means both the door leaf and the frame leaf are recessed into mortised pockets, producing a flush, clean installation profile. It is appropriate for single-action swing doors in corridors, utility rooms, and access areas. With 8 mounting holes split across the door leaf and frame leaf, the fastener pattern distributes load evenly across the door edge and frame rabbet.

• Spring mechanism provides automatic self-closing without a separate door closer

• 200 pound load capacity suitable for standard commercial interior doors

Compatibility

Designed as an OEM-style replacement or new-installation spring hinge for full-mortise door applications requiring a 3.5-inch door leaf height and 2-inch leaf width on both the door and frame sides.

Installation Notes

Installation is performed by a qualified door hardware technician or finish carpenter. The door and frame must be mortised to the correct depth before seating the hinge leaves to ensure a flush surface. Adjust spring tension only with the appropriate tension pin or spanner tool supplied or specified by the manufacturer, and keep fingers clear of the knuckle during adjustment. Follow applicable building and fire codes when replacing self-closing hardware on rated door assemblies.
