The Series 1100 provides joint restraint for PVC pipe-to-pipe joints, and it may be installed on new or existing systems. Joint restraints totally eliminate the need for thrust blocks. The restraints have internal serrations that lock onto the pipe and give 360 degrees of contact and pipe wall support. These restraints may be used with PVC pipe made to either a CIOD or IPS OD diameter regimen. See the table below for the product’s rated pressure.
