The safer, more dependable 2DH allows the chain on the boomer assembly to quickly adjust and securely lock these machines to their respective pipe sizes. The boomer assembly is now a captive member of these machines. During final assembly every machine is calibrated to .025 in concentricity and .015 in squareness, then checked one last time before distribution. A single thumbscrew secures the instrument instead of hose clamps. A cotter pin makes the thumbscrew a captive member of the torch holder, providing a mechanism for spreading the 7CS and allowing easy removal or replacement of the torch.
Solid performance is achieved every time.
The 7CS can now be easily retrofitted to existing 5C Torch Carrier Assemblies with only two screws required for removal and replacement.
