Reducing the time you need to attach your trailer, the Polar Trailer Coupler Kit lets you adapt your Polar HD Towing Trailers to fit 2-inch tow balls. Ready to help you easily attach your trailer to any 2-inch ball hitch, the coupling kit ensures you don't have to find a unique attachment for your trailer, saving you time and energy. The coupler fits to your trailer's 2-inch channel tongue to create a solid, secure attachment between your trailer and vehicle. A lockable trigger release allows for fast, secure hitching and detaching, keeping your payload firmly in place as you navigate your property or the road. Constructed with a zinc coating, the coupler kit resists wear and tear from regular use, perfect for almost any towing application. Designed to fit Polar Trailer HD Towing Trailer models, the coupler kit is compatible with the HD 1200/1500, HDM 1400, and HD Max trailers. Firmly securing your trailer to a tow ball, the Coupler Kit by Polar Trailer lets you link your Polar HD Trailer to more common tow ball hitches.
