Overview The Bonin Type YH170/YH170B is a heavy-duty Right Angle Coupler designed for connecting two 48.3mm scaffold tubes at 90 degrees. Unlike standard generic couplers, the YH170 is manufactured with precision tolerances favored by the British construction industry. It provides a rigid, vibration-resistant connection essential for complex load-bearing scaffolds.

Why Choose Type YH170/YH170B for Your Market?

  • Engineered for the UK Market (EN74 Compliant): Safety is paramount in the UK. The YH170 undergoes rigorous batch testing to ensure it meets or exceeds EN 74-1 requirements. Its robust drop-forged body eliminates the risk of brittle failure associated with lower-grade castings.

  • Superior Corrosion Resistance (For Middle East): For our clients in the Middle East (UAE, Saudi, Qatar), we offer a specialized Hot Dip Galvanized (HDG) finish. With a zinc coating thickness of 60µm+, the YH170 withstands extreme desert heat and high-salinity coastal air, ensuring a long lifespan and reduced maintenance for rental companies.

  • Enhanced Grip & Stability: The interior cap design of the YH170 maximizes contact area with the steel tube, providing superior slip resistance (≥15kN). This makes it ideal for heavy industrial formwork and offshore oil & gas platforms.

Recommended Applications:

  • UK: Commercial high-rises, restoration projects, and system scaffolding tie-ins.

  • Middle East: Oil refineries, infrastructure projects, and heavy-duty shoring.

FAQ

Q: What is the difference between this YH170/YH170B and the standard double coupler?

A: The YH170/YH170B is designed specifically as a “British Type” coupler. It typically features a slightly more robust body profile and higher grade bolts to meet the strict EN74 requirements favored in the UK market, whereas standard models may only target basic BS1139 compliance.

Q: Is the YH170/YH170B compatible with 48.3mm tubes in the UK?

A: Yes, absolutely. It is precision-engineered for standard 48.3mm OD scaffolding tubes (Type 3 and Type 4) commonly used across Britain and the Commonwealth.

Q: Can you mark our company logo on the YH170 coupler?

A: Yes, for bulk orders, we can emboss your brand name or standard marks (e.g., “EN74”) directly onto the coupler cover during the forging process.
