Abstract
An adjustable coupling structure for the support of lighting fixtures, pipe support racks, and the like utilizes an adjustable coupling device to couple two threaded support rods. The coupling device includes a clearance hole and a parallel threaded hole through a rigid body. The minor diameter of the threaded hole is tangent to the clearance hole thereby providing meshing of the threads of the two rods. Adjustment is provided by turning either of the threaded rods.
