These are the small parts that complete a tubular or cuplock scaffold: couplers, base plates, adjustable jacks and spigot pins. They are made to fit 48.3 mm OD scaffolding tube. Right-angle and swivel couplers join tubes at any angle. Adjustable jacks level the scaffold on uneven ground. Finish is electro-galvanised or hot dip galvanised, and the parts can be supplied with the system or separately.
