Abstract: A side beam pipe hanging bracket for principal use in fire sprinkler systems. In the first step of forming the bracket, a generally rectangular shape having an inverted-T-shaped slot, is cut from the metal strip, thereby defining a bolt receiving segment and two hanging segments, one to each side of the bolt receiving segment. The flat bracket is then stamped with threads along the bolt receiving segment, thereby causing the bolt receiving segment to curve and the hanging segments to move laterally toward one another. The hanging segments are then forced further laterally until they overlap one another and holes in each segment are aligned. This motion causes the bolt receiving segment to bend further into a channel with threads around its inner circumference capable of accepting a threaded pipe hanging rod. The bracket is mounted on the vertical surface of a horizontal support by extending a fastener through the overlapped holes in each hanging segment.
