Does not fit Gravenhurst 4" NON-perforated pipe!
This coupler fits the Gravenhurst 4" PERFORATED pipe, but its diameter is too large to fit inside and couple Gravenhurst 4" NON-perforated pipe. Go figure! You would have thought, like I did, that the perforated and non-perforated pipe would have the same inside diameter, but the non-perforated pipe has a slightly smaller diameter, too small to allow the use of this coupler. I wanted to connect a non-perforated 4" pipe to a perforated 4" pipe, both purchased from LOWES. Be warned that it won't work.
