Black Jack Trailer Jack has introduced a DO35 ball weight scale.

The precision-fit Black Jack DO35 Tow Ball Weight Scale is purposedesigned to suit the DO35 coupling. Simply position the scale underneath your trailer ' s DO35 coupling and lower the coupling to measure your towball weight.

DO35 hitches are designed to articulate north-south and eastwest. Using a ball weight scale that hasn’ t been designed to suit this coupling could be dangerous as the DO35 could articulate, causing the weight scale to slip.

The scale, which as a RRP of $ 89, also comes with an adaptor to suit 50mm ball couplings.
