Northland Fishing Tackle Snubber Stops - A neoprene rubber bobber/sinker stop that provides anglers the flexibility of moving their bobber or sinker any distance from the hook. Perfect for use as a slip-bobber and sinker stop for all species of gamefish. Neoprene rubber won't damage line. Allows easy adjustment of the distance between bobber or sinker and hook. When used as a sinker stop, it works great for live-bait walleye rigs as well as “pegging” a sinker to a hook Texas style for bass.
