Curt Trailer Ball Box Wrench

Our trailer ball box wrench is constructed from forged, hardened steel and has a durable chrome plating. It features two different ends to fit two trailer ball nut sizes. It can be used on trailer balls with either 3/4 in. or 1 in. shanks and has a six-point hex design for a better hold on the nut compared to 12-point wrenches. The CURT trailer ball wrench is the perfect installation tool to quickly get your trailer ball mounted and your trailer hitched up.
