HT Enterprises - Thermal Hole Cover

The Thermal Hole Cover works ideally with any tip-up! Simply slip the insulated foam material around the center tube or crossbar to prevent snow and light from entering the hole. The black material also absorbs sunlight and the thermal energy of the water to prevent the hole from freezing. Also included is HT's freeze proof tube, which prevents the Windlass from freezing up, even ton the coldest days!
