Hanger bar assembly
First Claim
1. A hanger bar assembly for supporting an outlet box between spaced apart support elements comprising:
- a first channel member being longitudinally slidingly engagable with a second channel member forming a longitudinally adjustable support bar, said first channel member having a plurality of longitudinally extending first grooves and a plurality of longitudinally extending first rails, said second channel member having a plurality of longitudinally extending second rails and a plurality of longitudinally extending second grooves, the first rails being slidingly received in said second grooves and said second rails being slidingly received in said first grooves such that rotational movement between said first and second channel members is resisted;
a clamping device for urging said first and second channel members into respective forced engagement thereby restricting movement between said first and second channel members; and
a securement device attached to said support bar for securing said support bar to the spaced support elements.

Abstract
A hanger bar assembly for supporting an outlet box between spaced apart support elements including a first channel member being longitudinally slidingly engagable with a second channel member forming a longitudinally adjustable support bar. The first channel member has a plurality of longitudinally extending grooves and the second channel member having a plurality of longitudinally extending rails slidingly received in the grooves such that lateral movement between the first and second channel members is resisted. A clamping device is provided for urging the first and second channel members into respective forced engagement thereby restricting movement between the first and second channel members. A securement device attached to the support bar for securing the support bar to the spaced support elements is further provided. The first and second channel members have apertures formed therein to accommodate fasteners for securing end plates to the support.
