The HoldRite® #117-L Series no-hub fitting restraints are designed to reinforce no-hub cast iron installations at 1/16, 1/8 and 1/6 bend changes of direction, in accordance with the installation instructions of US cast iron soil pipe manufacturers, CISPI Designation 301-18, 310-18 and the 2006 CISPI installation handbook. The #117-L (2 to 8 in) retain the elbow onto the adjoining piping using stainless steel bands which must be torqued to 60 in-lb minimum. When installed correctly, these restraint brackets achieve a safe thrust pressure rating equal to 50 ft head of water pressure. For sizes 10 to 15 in, heavy-duty steel pipe clamps and straps are used and require 60 ft-lb of torque on pipe clamp bolts.
