The Bonin Type YH166 is a robust German Style Double Coupler, engineered for heavy-duty scaffolding connections. Featuring a reinforced body and optimized grip, it connects two 48.3mm tubes at 90 degrees with superior stability. Designed specifically to meet the preferences of the German and European markets, complying with EN 74 and BS 1139 standards.

  • Model: YH166 (German Type)

  • Standard: EN 74 Class A / BS 1139

  • Nut Size: 19mm / 22mm (Optional)

  • Surface: HDG / EP / Paint

Key Features for the German Market:

  • Robust German Design: Unlike lightweight couplers, the German Type YH166 features a thicker forged cover and base. This design offers enhanced resistance to deformation under heavy loads, a critical requirement for German safety inspectors.

  • Standard Compliance: While fully compliant with BS 1139, this coupler is engineered to satisfy the rigorous performance criteria of EN 74 and is compatible with systems requiring DIN 4420 standards. It ensures a safe, rigid connection for tube and coupler scaffolds.

  • Customizable Nut Sizes (19mm / 22mm): We understand that German scaffolders often use different tools compared to the UK. We offer the YH166 with either 19mm (width across flats) or 22mm flange nuts to match standard German ratchet spanners.

  • Long-Lasting Surface: Available in Hot Dip Galvanized (HDG) finish to prevent corrosion in Germany’s varied climate, from rainy autumns to snowy winters.

Applications:

  • Industrial Plant Maintenance (Germany)

  • Heavy Construction & Formwork

  • Compatible with 48.3mm Steel & Aluminum Tubes

FAQ

Q: What makes this a “German Type” coupler?

A: The “German Type” (YH166) typically features a distinct shape that is slightly bulkier than the British type, often designed to be compatible with DIN standards. The most notable difference is the option for 19mm or 22mm nuts, whereas British couplers strictly use 21mm/23mm nuts.

Q: Is the YH166 certified for use in Germany?

A: Our YH166 is manufactured to meet EN 74 Class A/B standards, which is the prevailing standard in Germany and Europe. We perform strict internal QC to ensure slip force and failure load meet these requirements.

Q: Can I mix German Type couplers with British Type couplers?

A: While both fit 48.3mm tubes, it is not recommended to mix them on the same scaffold level due to different spanner sizes required (19mm/22mm vs 21mm) which affects worker efficiency.
