Scaffolding Couplers - Forged, Pressed & Built to BS EN

Fittings

Fittings

Duscaff manufactures couplers that conform to EN 74, BS 1139, standards.

Fittings are the couplers which hold the tubes together. The most common are called scaffold couplers, and there are three basic types: Right Angle Couplers, Swivel Couplers and Putlog Couplers. To join tubes end-to-end joint pins or sleeve couplers are used. Only Right-Angle Couplers, Swivel Couplers and Putlog Couplers can be used to fix tubes in ‘load-bearing connections’.

Some fittings might not be listed below as our range of scaffolding couplers is very vast. Write to us with your requirement as we stock most types of scaffolding couplers.
