National Hardware Squeak Guard residential door hinges with sealed pin bearings designed to keep interior doors opening and closing quietly. 1/4" radius rounded corners are the most common corner style on modern pre-hung interior doors - if your existing hinges have a slight curve at each corner rather than sharp square corners, this is almost always the right replacement.

Tip: When replacing existing hinges, match the corner radius of your old hinges before ordering. 1/4" radius is the most common modern interior-door style; 5/8" radius is the next most common. Lay an old hinge on top of one in the pack to confirm fit.
