Tube And Coupler
In Scaffolding. An assembly of heavy walled scaffold tubes used as verticals, horizontals and as angled braces, held together by purpose made bolted couplers.

tube and coupler scaffold

I can remember doing suspended slab formwork using only scaffold tubes for the supports, and we used to put double couplers under the load bearing transoms. How unbelievably primitive compared to today's shoring frames with snap together speed and adjustable screw jacks.

Likewise scaffolding systems have also advanced, but for some reason scaffold tubes and clips still seem to be hanging on. They will never be made obsolete altogether, because they can be used in many cases where modular systems are not convenient.

Above is a shot of a swivel coupler fixing a brace to the base of a standard. There are many different types of couplers, but they are all tightened using standardised size high tensile bolts. Swivel spanners are made specifically for scaffolders and they are extremely quick to use.
