Ringlock Scaffold Spigot Adapter Clamps

Ringlock spigot adapter clamp is also called scaffold spigot adaptors, ringlock support spigot clamps, spigot couplers, ringlock joint pin couplers, etc.
The product includes one ringlock spigot and one standard 48.3mm scaffold tube welded with a forged half scaffolding clamp. Between the spigot coupling and coupler tube, there is a set of bolts and nuts fixing them together.
In construction, the clamp of the spigot adaptor connects to the horizontal members of ringlock system scaffolding, like ringlock lattice girders, O-type ringlock truss ledgers, ringlock O ledgers, etc. While the spigot parts connect to scaffold standards, allowing vertical uprights erected.
Using the ringlock spigot adapter coupler, you can erect the ringlock standards at any intermediate position along the lengths of the ringlock horizontal parts.
