RESTRAINERS FOR PVC PIPE

300 SERIES	350 SERIES

Clow Canada's Series 300, 350 and 360 Restrainers provide a fast way to anchor PVC pipe to mechanical joint fittings, push-on fittings, and bell to spigot PVC pipe joints. They provide full 360 degree contact, with the gripping action of the serrated inside surface securing the clamp to the pipe. These restrainers provide high resistance to thrust force, and they eliminate the need for concrete thrust blocks or other restraining devices.

Clow's 300/350/360/390 Restrainers Superior Design/Construction Features

• serrations provide full circumferential grip on pipe, preventing point loading caused by use of foot pads
• side-bolt tightening provides even pressures on pipe, no pipe distortion * separate from mechanical joint, does not interfere with joint
• allows for pipe deflection
• only 2 side bolts, for easy inspection; no foot pads to inspect
• can be used with standard gland rings
• machined to pipe tolerances for better quality control

	Easy Installation	can be assembled above ground and lowered into trench
	Cost Effectiveness	eliminates contractor waiting time for concrete delivery and setting
	Easy Maintenance	mechanical apparatus; can be installed independent of joint for field repairs of future construction
	Versatility	ideal for poor soil conditions
	Durability	if corrosion protection is used on fitting, no further protection is required.
