3-1/2 in. Stainless Steel Square-Corner Door Hinge
A square-corner butt hinge in stainless steel, sized for residential interior and light commercial doors. Butt hinges mount in mortises cut into the door edge and the jamb so the leaves sit flush with the surrounding wood, leaving only the barrel and knuckle visible when the door is closed.
Square corners suit mortises cut by hand with a chisel or routed with a square-corner template, and they match the pockets found on most older jambs and prehung units that were not machined for radius-corner hardware. Stainless steel resists rust and staining, which makes it a reasonable choice for bathrooms, kitchens, laundry rooms and exterior openings where plated steel hinges tend to corrode.
Hinges are sold and installed in sets, with most passage doors carrying a pair and heavier or taller doors carrying three. The size given refers to the square leaf dimension when the hinge is open.
