These 48mm Key Clamps are designed to fit 48.3mm outer diameter tube. Industry standard 1.1/2" Galvanised Nominal Bore tube (which is also used for scaffolding) is the standard tube that is recommended for use with these fittings. However, any tube within the 47-50mm range in most solid materials should suffice. If you are unsure that a tube that you already have and would like to use will fit, give us a ring and we will try to determine if it will suit.
