Product Q&A
Q:What is a Scaffolding Swivel Coupler?
A:
A Scaffolding Swivel Coupler is a key forged steel fitting used to connect two scaffold tubes at any angle. Its unique pivoting design allows independent rotation, enabling secure, non-parallel connections for rigid three-dimensional structures.
Q:What materials are your swivel couplers made from?
A:
We use premium Drop-Forged Carbon Steel (Grade Q235B or S235JR) for the body for superior grain structure. Bolts and nuts are Grade 8.8 High-Tensile Steel, hot-dip galvanized for maximum corrosion resistance.
Q:What scaffold tube sizes are they compatible with?
A:
Standard couplers are designed for the global industry standard tube: 1-1/2 inch (1.5') with an Outer Diameter of 48.3mm. Other sizes like 42mm OD and 60.3mm OD are available upon request.
Q:How is it installed and tightened correctly?
A:
Place tubes into the jaws, ensuring no gaps at the heel. Hand-tighten the bolt, then use a scaffolding spanner to reach the recommended torque of ~40-50 Nm. Avoid overtightening to prevent damage.
Q:What is the difference between a Swivel Coupler and a Double Coupler?
A:
A Swivel Coupler connects two tubes at any angle (one fixed, one adjustable). A Double Coupler connects two tubes in parallel, end-to-end. They are complementary fittings used together in complete systems.
