Now you finally have the upgrade you've been looking for. CFCT has created a replacement spool that is specifically designed to replace Beaver Dam spools, both with the bottom nut and side set screw. Our new spool has the features to make your tip up catch more fish and work better. It has a large arbor, designed to hold 50-60 feet of regular non-coated tip up line instead of 50 yards. It has a built-in handle eliminating the need for add on handles or tools. Finally, it has an arbor knot hole which the arbor knot can be tied through, eliminating the need for tape and prevents line slippage on the spool. This spool should replace any spool with a 1/8” drive shaft and removable bottom threaded nut. Visit CFCTackle.com for more details.
