The Standard Towing Head is a
simple device that attaches to the end of a piece of pipe
to allow it to be pulled. It is designed for use with polyethylene pipe of wall thickness between *SDR11 & SDR17.6. (Other materials and wall thicknesses can also be accommodated) It is operated by simply inserting in to the pipe and turning the eyebolt. The turning action draws a cone into four toothed segments which are forced into the wall of the pipe. The harder the eye is pulled the harder the pipe is gripped. The grip is so good that it is possible to stretch the pipe! |
