This Trailer-to-Trolley Coupling adaptor simply bolts on to a standard 1" (25.4m) box section road base and allows you to attach your trolley and/or carry a shorter/smaller trolley such as Oppi, Topper, Cadet or Mirror.

Suitable for coupling trolleys featuring a tubular coupler to a 1" (25.4mm) box section trailer. The U channel used on the coupler is 27mm wide to allow it to comfortable fit on a 1"(25.4mm) trailer box section.
