This 50mm ball type fixed coupling is designed to be used on trailer up to 2500 kg
ATM (Aggregate Trailer Mass) and with a maximum tow ball weight of 250 kg.
This unique product incorporates a clamping system that grips the sides of a specially designed 50 mm tow ball and resists movement to stabilise the trailer.
This is particularly a benefit when large trailers such as caravans are buffeted by side winds or by a passing truck and trailer combination.
NOTE: This type of coupling must only be used with a 50mm ball which has an anti-rotation plate for attachment to the vehicle fitted.

When used in a commercial or defence department application, often a 75 mm ring type towing eye is requested.
This style of coupling is similar in function to ball type couplings (fixed and over ride ) but instead of the connection to the tow vehicle being a standard 50 mm ball, the connection is a 75 mm inside diameter ring and this attaches to a “pintle hook” fitted to the tow vehicle. These types of couplings are primarily used in applications where the tow vehicle is a heavy commercial truck. As the Australian Standard AS 4177 states the 50mm towball to have a maximum capacity of 3500 kg AT M (total loaded mass), ring couplings are used when higher loads are involved.
