This 5'x7' is designed for the fishermen who likes to move fast between spots. The trough holes are large rectangular shaped holes... much like a spear hole .. with a hinged cover that lays flush when not open. The larger opening is a benefit when you are drilling through thick ice or when you want to drill holes fast. If you like to drill your holes and then back your house over the holes, this system makes that step super easy!
