The Frabill Pro Thermal Tip-Up, 1671, serves as a reliable way to protect your fishing hole. The round shape and thick insulation of the Frabill tip-up with life chart covers the hole in its entirety, preventing it from freezing over even in sub-zero temperatures. The Frabill cover also prevents snow and slush from entering the hole and also keeps out excessive sunlight so that fish are not driven away. The bright yellow color of the Frabill cover makes it highly visible. Pre-lubed with low temperature lubricant, the Frabill Pro Thermal Tip-Up, 1671, also features a removable spool shaft and a shaft design that allows easy re-greasing.
