ABSTRACT:
A coupler for structurally joining opposing ends of overhead support rails is disclosed herein having a pair of elongated splice plates carried on opposite sides of the rail ends so as to overlap the abutment of the ends. Each splice plate of the pair is of substantially uniform cross section having a U-shaped channel section including a central, upright web terminating in transverse, parallel flanges. The upper flange is integrally formed with an upwardly extending flange parallel to but spaced apart from the upright web. Trapezoidal ribs extend externally of the channel section in parallel spaced relationship along the upper flange immediately adjacent to the web and along the web midway between the transverse flanges. Threaded bores provided in the ribs insertably receive fasteners for bearing against the respective rails. The configuration of each splice plate is conformal with the external configuration of the overhead support rails.
