ABSTRACT:
A system for supporting loads includes a track having uniformly spaced apertures separated by necks. A bracket is mounted on the track and has two groups of studs which are positioned in the necks and prevent the bracket from pulling away from the track. Neighboring studs in both groups have identical center-to-center spacings. Two plugs pass through holes in the bracket and into respective ones of the apertures. The plugs fix the bracket against movement relative to the track longitudinally and transversely of the latter. The distance between a plug hole and any stud equals one-half the center-to-center spacing of neighboring studs of a group or an integral multiple of one-half such spacing. A locking member passes through an additional hole in the bracket and frictionally engages the track to prevent the plugs from pulling out of the respective apertures during an impact.
