This part is from the incredibly versatile range of galvanised malleable iron slip-on pipe and tube fittings produced by Interclamp.
They allow for quick and easy construction of different types of structures with the use of a simple hexagon key, rather than any complicated fixings.
Typically, these parts are used to construct hand rails and safety guardrails, but they are also suitable for a huge range of other structures such as playground equipment, shop fitting, sports practice nets, greenhouses, exhibition stands, wheelchair access ramps, and much more.
