Mustad Weight Stops are used to keep your weight pinned closely to your bait when fishing heavy cover techniques. Compatible with a variety of line-through style sinkers such as worm weights, flipping weights, and punch weights made from various materials, these weight stops wont damage your line the way other weight pegging techniques like crimping and toothpicks can. Pegging your weight can be crucial to getting your bait down through heavy cover to where the big bass live!
