Overview The Bonin Drop Forged Swivel Coupler (Type YH158S/YH158DS) is a versatile load-bearing fitting designed to join two scaffold tubes at flexible angles. Unlike fixed right-angle couplers, the swivel coupler features a high-strength center pin that allows for 360-degree rotation. This makes it the ideal solution for installing diagonal braces (cross-bracing) or connecting tubes in non-rectangular scaffolding layouts.

Why Choose Bonin Swivel Couplers?

  • Flexibility & Safety (BS1139 Compliant): Manufactured to meet stringent BS 1139 and EN 74 safety standards, our swivel clamps ensure a non-slip connection even under heavy loads. The drop-forged steel construction prevents deformation, ensuring structural stability for high-rise projects.

  • Tailored for Global Markets:

    • For the Middle East: We recommend our Hot Dip Galvanized (HDG) finish (Min 60µm zinc coating) to withstand extreme heat and saline environments, preventing rust and seizing.

    • For Europe: Our Electro Plated (EP) option offers excellent performance and cost-efficiency for standard climate conditions.

  • Precision Engineering: The swivel mechanism is secured with a heavy-duty rivet, ensuring smooth rotation during installation while maintaining high shear strength once tightened.

Key Applications:

  • Diagonal Cross-Bracing (Ledger to Standard)

  • Circular or Irregular Scaffolding Structures

  • Facade Support & Formwork Reinforcement

  • Construction sites in UK, Germany, UAE, and Saudi Arabia

FAQ

Q: What is the main difference between a Double Coupler and a Swivel Coupler?

A: A Double Coupler locks tubes at a fixed 90-degree angle (Right Angle) and is used for the main load-bearing structure. A Swivel Coupler allows for 360-degree rotation, primarily used for adding diagonal braces to prevent the scaffold from swaying.

Q: What is the slip resistance of your BS1139 Swivel Coupler?

A: Our drop forged swivel couplers are tested to exceed the EN74 Class A requirement, offering a slip resistance of ≥ 12.5 kN, ensuring maximum safety for workers.

Q: Do you export to the Middle East?

A: Yes, we regularly export HDG swivel couplers to markets like UAE, Saudi Arabia, and Qatar. We understand the specific packaging and SGS inspection requirements for these regions.
