Cruisemaster DO45 Plus 4.5T (With Handbrake & Bolts) Off Road Pin Coupling

The DO45 is the big brother of the DO35. Caravans up to 4.5 tonnes can have the benefit of a heavy-duty off-road WDH compatible hitch. This coupling also incorporates a double automatic locking mechanism, massive articulation in all directions simultaneously and the patented self-aligning pin. 

In addition the DO45 has some new features. These include a safety dust cover which ensures that when fitted the coupling is correctly locked and ready to go. As well as this a front cushion is fitted to reduce any damage to the tow vehicle should the coupling process be taken a bit ambitiously. The drop-on facility come into its own when trying to couple up on uneven and soft surfaces where trying to level up the tow vehicle and caravan or camper trailer can be extremely difficult.

Like all Cruisemaster™ products our couplings range is designed and tested to perform under Australian Conditions. Each year, Cruisemaster™ vigorously remote area test new coupling designs and features with highly sophisticated Motec Data logging technology such as temperature sensors, G-force sensors, height sensors & comprehensive GPS tracking software.

*Please note while the DO45Plus’s Zn-Ni with E-Coat provides superior corrosion protection it may fade with extended exposure to UV. This does not affect the operation of the DO45Plus. To best maintain the finish of the product, we recommend covering the DO45Plus coupling when not in use if stored outside and exposed to direct UV.
