42mm Pipe Clamp Fittings are designed to fit industry standard 1.1/4″ Galvanised Nominal Bore tube, which has an outer diameter of around 42mm (42.4mm).

42mm fittings can be used for many purposes, but 42mm is ideally suited to the DIYer or tradesperson building framework, safety barriers, guardrails or tables and desks.

The steel pipe that we sell here is the recommended type for use with these size fittings. However, most steel tube within the 41-43mm range should suffice. (Call us for clarification if unsure)

All fittings are galvanised mild steel, and come complete with grub screws to be tightened with an allen key.
