Example of our 00650 series in action

Duct pullers are also a very important part of pull back operation.  The most common attachment used to be a couple of holes through the end of the duct with nuts and bolts passed through a pull chain.  This put the entire load of the pull on the holes drilled through the duct, and was, for that reason, quite ineffective.  Today, every duct manufacturer recommends the use of a puller that distributes the load around the entire circumference of the duct.

Hence the birth of the duct puller.  Also called a towing head or pipe pulling eye, its purpose is to attach PE/PVC ducting to the pullback swivel.   The most common type of puller has a set of wedge shaped teeth on a conical mandrel that is inserted inside the end of the duct.  As the mandrel is pulled forward, it forces the teeth outward causing them to grip the inside wall of the duct. 

There are various methods of doing this (duct pulling) and DCD offers a wide variety of options.
