Swivel Coupler
• Multi-angle connection: Makes steel tubes to form non-90° angles in horizontal or vertical direction, adapting to complex frames.
• Torsional load-bearing capacity: Fastened by rotating joint and bolts, resist the torque generated by diagonal loads.
• Dynamic adjustment: Bolts can be loosened to adjust angle during erection. After positioning, it’s tightened to form a rigid node.
Product details
Swivel couplers are used for the connection of two components that intersect at any angle, including diagonal brace and vertical standard or horizontal ledger, as well as parts where the angle needs to be flexibly adjusted. It is composed of two rotable half couplers, central pin shaft, bolt and anti-loosening washer. The coupler acting surface is provided with anti-slip patterns. The pin shaft and bolt are made of carbon steel and quenched to prevent rotational abrasion. The swivel coupler is a key component in the scaffolding system that enables the connection of steel tubes at any angle.
