The side outlet tree fixing is often used in large tubular structures with the upright passing through the fitting.
The through tube, the vertical piece in the image, cannot be joined within the fitting and must be continuous.
Dimensions shown are in millimetres.
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.
