The Finicky Fooler Hole Cover & Rim is a new concept in hole covers.  The key to effectively keep the hole from freezing is to minimize outside air from filtering in, which is difficult to do with conventional hole covers.  Constructed of styrofoam. Our cover utilizes an insulated rim that is centered over the ice hole, and slush is then packed around the perimeter to provide a seal.  The hole cover seats inside the rim, sealing off outside air.  The rim provides a 1” perimeter of insulation and the cover provides ¾” of insulation.  Can easily be used with an underwater tip-up.
Dimensions:   11” O.D. x 9” I.D.  x 2” H.  Fits 10” hole or smaller and 2 rims and hole covers fit inside a 5-gallon bucket.
