The Bonin Type YH122 is a Heavy-Duty Pressed Double Coupler, manufactured from extra-thick 5.0mm steel plate. Designed to bridge the gap between standard pressed fittings and drop-forged couplers, it offers superior strength and deformation resistance. Fully compliant with BS 1139 standards, making it a cost-effective, high-performance solution for the European market.

  • Type: Pressed Right Angle Clamp (Heavy Duty)

  • Thickness: 5.0mm (vs standard 3-4mm)

  • Standard: BS 1139

  • Surface: Electro Plated (EP)

Why Choose the 5mm YH122 for Europe?

  • Heavy-Duty Performance (5mm Thickness): The extra steel thickness provides a firmer grip on the tube and higher slip resistance compared to standard pressed couplers. It offers a “solid feel” that European scaffolders appreciate, closer to the performance of a forged coupler but at a lower price point.

  • BS 1139 Compliance: Manufactured to meet BS 1139 specifications, ensuring safety and compatibility with standard 48.3mm tube and clamp systems used across the UK and mainland Europe.

  • Cost-Effective Durability: For projects where Drop Forged couplers (Class A) exceed the budget, the YH122 provides the perfect balance. It is strong enough for general purpose scaffolding, fencing, and light construction duties.

  • Corrosion Protection: Finished with Electro Plating (EP), providing a clean, bright appearance and basic rust protection suitable for indoor or temporary outdoor structures.

Applications:

  • General Scaffolding & Maintenance

  • Temporary Fencing & Enclosures

  • Cost-sensitive projects requiring BS1139 compliance

FAQ

Q: Why should I buy the 5mm pressed coupler instead of the standard 4mm?

A: The 5mm thickness provides significantly higher resistance to deformation. When scaffolders tighten the bolt, standard 3-4mm couplers can sometimes bend out of shape. The 5mm YH122 maintains its shape, ensuring a safer, tighter grip on the tube.

Q: Is this as strong as a Drop Forged coupler?

A: While Drop Forged couplers (EN74 Class A) are the strongest option for heavy industrial loads, the 5mm Pressed Coupler is a “Heavy Duty” version of the pressed range. It is an excellent alternative for medium-duty applications where you want to save cost without sacrificing too much strength.

Q: Can this be used in the UK?

A: Yes, as it is designed to BS 1139 standards. However, for major structural scaffolding in the UK, Drop Forged (EN74) is often specified. The YH122 is ideal for auxiliary uses, independent scaffolds, and residential projects.
