I bought this to mount a Botex socket splitter. Firstly, this clamp is strictly only suitable for 50mm pipes, not 48mm. For me, this is a bit inconvenient, but bearable. Secondly, this clamp uses an M10 bolt with a specific head that you don't often see. It is too small and narrow, and if I lose it, I don't even know where to look for it. Otherwise, two of these clamps hold the splitter very strong, and I am happy with the purchase.
