The confidence to extend and expand your railings.

Whether you need an internal spigot for a flush joint or a rigid connection which may have to withstand a direct tensile load. Whether you want to replace a damaged section of railing or to simply extend your rail beyond conventional size. Our couplings will help you get there. From Kee Klamp couplings made from Hot dip Galvanised malleable iron to Quick Rail couplings made from the most corrosive resistant aluminum alloy available, to internal locking splices, modular caps and friction fit couplings – this is the one-stop for all your railing coupling needs.


  • Internal spigot couplings for providing a flush joint between two tubes of the same diameter.
  • Sleeve joint couplings for providing an in-line joint between two tubes of the same
  • Mend-a-rail coupling, modular external coupling, friction-fit Internal coupling & locking splice.
  • All coupling connectors are industry standard, durable, non-corrosive and easy to install.
  • Flexibility to use with any pipe, reusable, high-strength fittings. Only a hex-key needed to fit.
