4" QL Head (Shell) - Excluding Blades

The 4” Bursting Head Shell is the front part of the assembly that bursts the old or damaged pipe, and creates room for the replacement pipe to be pulled into place. The Shell takes two 4” Blades (TT-HEAD-4BLD) that are held in place with Screws (TT-FSNR-BA500F), so they are replaceable when they become dull or damaged. This a spare or replacement part, and does not come with any other components of the assembly.
