The classic and versatile ball tip door hinge has been a favorite since the late 19th century. Our authentic reproduction hinge has a loose pin with attached finial, slotted wood screws, and heavy duty 1/8" thick leaves - just like the originals. Made of solid extruded brass for high strength and durability. This 3 1/2" size hinge works for most standard interior doors. Dimensions: 3 1/2" x 3 1/2" not including ball finials. Leaf thickness is 1/8".
