Scaffolding Couplers – Inner Joint Point

Scaffolding couplers, also known as clamps, are used in tubular scaffolding systems as fittings. Vertical tubes are connected to horizontal tubes via right-angle clamps. Diagonal tubes are periodically connected to the scaffold via swivel clamps in order to stabilize the scaffold. Tubular scaffolding is a traditional system but is the most widely used worldwide.

And the inner joint pin is used as a joint to connect two pipes end to end from the inside of the pipes.
