US Patent 7413156 Hanger bar for fixture and method

A hanger bar attachable between joists for supporting a fixture has an attaching plate at distal ends with a contact portion for bearing against a joist and a laterally extending portion that defines a recess. The extended portion defines an elongate slot that receives a bushing and a fastener extends through the bushing for securing the elongate bar to the joist. The hanger bar is selectively positionable after initial attachment to the joist by moving the attaching plate as guided by the bushing in the slot. A method of attaching a hanger bar to joists for supporting fixtures is disclosed.
