Scaffolding Couplers

Scaffolding couplers and clamps are essentially the fundamental component that is used to assemble tube-and-coupler scaffolding as encompassed by AS1576. Tube-and-coupler scaffolding is defined in AS1576.3 as 'a scaffold in which individual circular tubes serving as standards, ledgers, braces or ties are joined together by means of purpose designed couplers'. This basic fitting that is designed to join two scaffold tubes can be used to create a diverse range of scaffolding structures or used as an accessory to prefabricated scaffolding systems. This manual includes basic types of scaffold couplers which join two tubes together as well as special couplers used to connect scaffold tube to other components, equipment or structures.
Working Load Limits (WLL’s) are given for couplers that are covered by AS1576.2 and comply with that standard. WLL’s for couplers shown may be limited by components to which they are attached. Hence, load capacity of such components must be checked for suitability to support resultant loads.
