Doesn't really fit 4in hub unless you trim the fins off, then it fits great.

The rubber fitting to convert a 4” cast iron hub to 4” ABS worked well. Experience really helps to install them. It should be installed half way on the plastic pipe first and then hammered into the cast iron hub. A lot of lubricante helps too.

      Under Rated Clamps
      These work great for joining a pipe in the middle where you cannot make any other fitting work. However, the band clamps are supposed to be torqued to 60 inch pounds (5 foot pounds). Mine came with Ideal-Tridon 1/2" wide worm gear clamps. Using the wrench designed for torqing just to 60Inch pounds for these clamps, one gave out before it got there. None of the others (eight total - two fittings) looked or felt quite right. I bought a beam type inch pound torque wrench so I could read visually. The single torque tool does about 45 inch pounds at which the clamps are already twisting sideways. I called Fernco about the clamp spot welded to the stainless shield that failed at about 30 inch pounds. I would have to be transferred to others who aren't available and go through multiple recalls to try to get a warranty replacement. AND, NO. I AM NOT TAKING EVERYTHING APART TO RETURN TO HOME DEPOT! I'll just order another 1056-33rc and use the center shield (SRC-15) off of it to put spare parts on my current fitting AND NEVER BY ONE OF THESE AGAIN.
