Creating a Custom Corner Bracket

Turn joist hangers into right-angle corner brackets

Metal joist hangers provide a quick, easy way to attach floor joists to ledger boards, cross beams, and header joists. But with a slight modification, you can turn these handy hangers into right-angle corner brackets.

Use tin snips or a hacksaw to cut the sides of the joist hanger from its squared-off bottom end. Discard the bottom piece, but save the two side pieces; each one can serve as an extra-strength corner bracket. Nail or screw the metal bracket to the inside-corner joint between two boards, as illustrated.

Joist hangers are available in various sizes for use with lumber ranging from 2x4 to 2x10. These hangers will yield corner brackets ranging from about 3 to 8 inches long.
