Trojan Coupling 3500kg 50mm GEOMET

Specifications

Measurements

Compatibility

• Towball: 50mm only. For a 1-7/8" towball, use the 1-7/8" version. Your towball and towbar must also be rated for the trailer's weight.
• Brakes: electric brakes or a driver-operated brake system, such as the Elecbrakes EB2. It has no override mechanism, so it won't operate surge (override) brakes.
• Weight: up to 3,500kg.
• Drawbar: suits drawbars drilled to the TC40 182 x 54mm pattern. Measure your existing hole centres before ordering.
