GHG Keel Grabber J-shaped weights attach to any style decoy and are held in place by rubber stretchee cords. They are very convenient and allow you to transport and store your decoys without the weights and cords becoming tangled. Stretch cords allow you to get the decoy line wound tightly around the keel, then stretch the end to hook the weight around the neck or around the front of the keel, keeping your decoys from tangling.
