Abstract

A system for positioning and supporting a pipe or conduit in fixed position relative to a structural element, comprising a support bar to be secured to the structural element having openings therein spaced at regular intervals lengthwise of the bar, and a thin flat bracket member to be affixed to the support bar in a selected position lengthwise of the bar. The bracket member is formed with at least one L-shaped lug and is adapted to be inserted through a selected opening of the support bar and moved relative to the bar from a preliminary position to a final position wherein the lug extends beyond the opening and overlaps the bar with a marginal edge portion of the opening received in the space between the lug and the bracket member. A locking member integral with the bracket member is adapted for movement through another opening of the support bar when the bracket member is in its final position thereby to affix the bracket to the support bar in a selected longitudinal position with respect to the bar without the use of separate fasteners.
