• Ideal for restraining hub-less cast iron soil pipe against separation during high thrust conditions Engineered to meet plumbing codes, pipe manufacturers' installation instructions, and CISPI installation handbook Installs in minutes Built with stainless steel, black iron and/or galvanized components No special tools required for installation No field cutting or modifications required

The HoldRite® #117-K Series no-hub fitting restraints are designed to reinforce no-hub cast iron installations at 90 deg (1/4 bends and short sweep 1/4 bends) 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-K (2 to 8 in sizes), retain the 90 deg 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.
