Trailer Coupling 50mm Spring Damper 2000kg Cast Iron

A 50mm trailer coupling built for towing setups that use a standard 50mm tow ball. It has a heavy duty nodular cast iron body, a spring damper, and a 2000kg capacity, making it a practical choice for replacement or new trailer builds where secure coupling matters.

Used for connecting a trailer to a vehicle, this tow coupling suits general towing, trailer maintenance, and repair work on utility trailers, plant trailers, and other standard towing applications. For anyone replacing a worn hitch or assembling a trailer from parts, the 50mm ball fitment makes it relevant for common UK towing setups. It is also useful for workshop fitting jobs where matching the correct ball size and load rating is an important part of safe trailer use.

The cast iron construction gives the coupling a solid, heavy duty build, while the zinc plated finish helps protect the surface in day-to-day outdoor use. A spring damper is included as part of the coupling design, helping make it suitable for regular towing use where dependable connection hardware is needed. The stated 75mm width is useful when checking fitment against an existing drawbar setup, and the 2000kg capacity gives a clear guide when matching the coupling to the trailer specification. It is compatible with tow balls CT2001, CT5168 and CT5590, which helps when replacing parts and keeping the towing setup matched correctly.
