ABSTRACT:
A hanger for supporting pipes below steel reinforced concrete slab foundations provides an elongated bendable shaft which can be connected to the reinforcing steel of a formed slab foundation prior to the pouring of the concrete. An open loop is secured integrally to the bottom portion of the shaft at a point of beginning, the loop having a curved generally circular body of less than three hundred sixty (360.degree.) degrees which terminates at the point of beginning and at a loop-free end. A radial strut extends from the loop-free end and away from the circular loop along a radial line originating at the loop center. Manual pressure applied to the bottom portion of the shaft and to the radial strut can close the loop by aligning the strut and shaft together in side by side relation. The loop can be closed permanently by a closure ring which can slide upon the aligned portion of the radial strut and elongated shaft so that the loop can be retained in a closed position.
