Abstract

A single entity toolless rafter or joist hanger has a claw with pointed spaced arms forming a mouth in which a conventional wooden base member is inserted. A hook on the other end of the hanger provides a loading surface formed with a force point disposed on an axis laterally offset from the normal vertical axis of the base, thereby promoting a firm gripping action. Automatic locking is achieved by a pivoted arm which gravitationally abuts against the side of the rafter or joist. The hanger is selectively removable simply by raising the pivoted arm and counter rotating the hanger to disengage it from the wood.
