National Hardware Squeak Guard residential door hinges with sealed pin bearings designed to keep interior doors opening and closing quietly. Square corners suit door jambs that were originally cut for square-corner hinges, so this set is a direct one-for-one replacement when you do not want to recut the mortise.

• Size: 3-1/2" x 3-1/2"
• Corner style: Square (sharp 90-degree corners)
• Finish: Matte Black
• Pack of 3 hinges (typical pack for one interior door)
• Surface-mounted - mortises into the door jamb and door edge
• Mounting screws and instructions included
• National Hardware Squeak Guard model N830-445

Tip: When replacing existing hinges, match the corner style of your old hinges before ordering. Square-corner hinges and radius-corner hinges are NOT interchangeable without recutting the door jamb mortise. Lay an old hinge on top of one in the pack to confirm fit.
