This Trailer-to-Trolley Coupling Adapter simply bolts on to a standard 1.5" (38.1mm) 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 1.5" (38.1mm) box section trailer. The U channel used on the coupler is 40mm wide to allow it to comfortable fit on a 1.5" trailer box section.

NOTE: Please measure your existing box trailer box section to ensure that it is 1.5" (38.1mm)
