National Hardware Squeak Guard residential door hinges with sealed pin bearings designed to keep interior doors opening and closing quietly. 5/8" radius rounded corners are a deeper rounded corner style found on many older pre-hung doors - if your existing hinges have a generous curve at each corner, this is the right replacement to match the existing mortise.

• Size: 3-1/2" x 3-1/2"

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.
