The HOLDRITE® #117-CE Series No-Hub Fitting Restraints are designed to reinforce no-hub cast iron installations in accordance with the installation instructions of U.S. cast iron soil pipe manufacturers, CISPI Designation 301-18, 310-18, and the 2006 CISPI Installation Handbook. The #117-3CE thru #117-8X6CE retains the Combo or Wye fitting onto the adjoining piping when positioned at the end of the line and when either a blind plug or a cleanout is installed. All stainless steel bands must be torqued to 60 in/lbs minimum. When installed correctly, these restraint brackets achieve a safe thrust pressure rating equal to 50' head of water pressure.
