After trying this coupling, I am extremely dissatisfied with its level of quality. The parts don't fit correctly, making it difficult to use. Despite following the instructions, I was left with a poorly clamped joint that broke apart after minimal use. The only pro is that it arrived quickly after ordering, but this product is not worth the money. Don't waste your time and money on the Climax 2C 037 Two Piece Clamping Plating.
