Hot Selling BS Standard Metal Casting Scaffolding Accessories Double Coupler

A Scaffolding Swivel Coupler (also called a Swivel Clamp or Right-Angle Coupler) is a key forged steel fitting used to connect two scaffold tubes (pipes) at any angle. Its unique pivoting design allows the two jaws to rotate independently, enabling secure, non-parallel connections essential for building rigid three-dimensional scaffolding structures.

We manufacture them from premium materials for maximum safety and durability: Body: Drop-Forged Carbon Steel (Grade Q235B or equivalent S235JR). The forging process provides superior grain structure and impact resistance. Bolts, Nuts & Washers: Grade 8.8 High-Tensile Steel, hot-dip galvanized. Standard Finish: Hot-Dip Galvanizing (HDG) to ISO 1461 / ASTM A153 for maximum corrosion resistance on construction sites.

Our standard couplers are designed for the global industry standard tube: Nominal Bore: 1-1/2 inch (1.5'). Outer Diameter (OD): 48.3mm. Other Sizes: Available for 42mm OD, 60.3mm OD (2-inch), and other specifications upon request.

Proper installation is critical for structural integrity: Place the two scaffold tubes into the jaws of the coupler. Ensure the coupler sits squarely with no gaps at the heel (where the tube meets the coupler body). Hand-tighten the single high-tensile bolt and nut. Final tighten using a scaffolding spanner (wrench) to the recommended torque (~40-50 Nm). Overtightening can damage the coupler or tube.
