This receptacle is installed on the back of your stationary structure and accepts a Camloc 4002 Series Heavy Duty Stud (sold separately). This special floating receptacle allows for some misalignment between panels. The receptacle can move a total of 1/16" (1.6mm) side-to-side. The depth does not change. 1/8" diameter rivet holes are spaced 1.00" apart.
