The Standard Towing Head sits flush up against the end of the PE pipe. The rest of the assembly sits totally inside the pipe. The eyebolt - which is a specially forged, single piece, high tensile steel eyebolt - is rotated to retract the tail component. This expands out the gripper rings for a tight secure grip inside the pipe. SDR 17.6 & 11 in the one piece.
