Pressed Swivel Coupler (5mm Heavy Duty) – Type YH122S | BS1139

The Bonin Type YH122S Swivel is a Heavy-Duty Pressed Coupler designed for flexible scaffolding connections. Constructed from extra-thick 5.0mm steel, it offers significantly higher durability and deformation resistance than standard pressed clamps. Featuring a strong central rivet for smooth 360-degree rotation, it is the robust, cost-effective choice for European diagonal bracing applications requiring BS 1139 compliance.

  • Type: Pressed Swivel Clamp (Heavy Duty)

  • Thickness: 5.0mm (Reinforced)

  • Function: 360° Rotation / Diagonal Bracing

  • Surface: Electro Plated (EP)

Overview The Bonin Type YH122S Swivel Coupler is the “Heavy Duty” variant of our pressed fittings range. Engineered with 5.0mm thick steel plates, this coupler bridges the performance gap between lightweight pressed clamps and expensive drop-forged fittings. It allows two scaffold tubes to be connected at any angle, providing a rigid yet flexible solution for cross-bracing in European construction projects.

Key Features for the European Market:

  • Robust 5mm Construction: Standard pressed swivel couplers (3-4mm) can sometimes deform under high torque. The YH122’s 5mm body ensures the clamp maintains its shape, providing a secure grip on the tube that feels comparable to a forged fitting.

  • Reinforced Center Rivet: The weak point of any swivel coupler is the rivet. The YH122S utilizes a high-strength shear rivet specifically designed for the heavier 5mm body. This ensures the coupler rotates smoothly during installation but holds firm under load without loosening.

  • BS 1139 Safety Compliance: Designed to meet the slip and distortion requirements of BS 1139, offering peace of mind for site managers and safety inspectors in the UK and EU.

  • Economic Advantage: Ideal for projects that require sturdy connections (like temporary fencing, lighting rigs, or general access scaffolds) where the full specification of EN74 Class A forged couplers is not mandatory, helping you save on budget without compromising safety.

Applications:

  • Installing Diagonal Braces (Ledger to Standard)

  • Creating irregular shapes or circular scaffolds

  • General construction and maintenance in Europe
