Suitable for 48mm diameter steel or aluminium tubes, these scaffolding clamp variations (also known as cheese boroughs or pipe couplers) are supplied with an electroplate finish. They are useful for quickly creating grids, frames and towers for lighting or scenery from standard tubes in stage rigging.
Based on the British Standard EN 74-1:2005, the main types of scaffolding clamps are:
Right angle coupler[BEST seller]: Two tubes crossing at a right angle (fixed 90°)
Swivel coupler: Two tubes crossing at any angle
Parallel coupler: Two tubes parallel to each other
Sleeve coupler: Two tubes end to end coaxially
Note: These couplers/clamps are not recommended for permanent installs.
