Berkley Duncan Loop Knot Animation

The Duncan loop is a great way to improve the action of your lure. While not needed for all types of lures it works exceptionally well with crankbaits and any other lure that needs some extra action. By tying your crankbait on with a loop knot, the lure works more freely and the natural action of the bait is greatly increased. Crappie and bream jigs hang better and also move more freely. This little bit of extra action can make a big difference.
