Replacement coupling designed for Ifor Williams Car Transporter Trailers. This coupling is compatible with all 3500kg Ifor Williams Car Transporter Trailers, but not with 1400kg, 2000kg, or 2600kg models. It is suitable for CT177 models and features a cast hitch head with an integral lock. The lock can secure the trailer when detached from the tow vehicle or prevent unauthorized removal when coupled. It fits standard 50mm tow balls and comes complete with a handle, pad, and clamp for a 48mm Jockey Wheel. The coupling is ready to install without needing assembly and includes a pre-fitted secondary coupling cable and guide. It is designed for use with auto-reverse brake systems.
