This 12 pack of 4 ounce J weights and stretch cords means an end to tangled decoys and fumbling around in the dark. The nylon pull fitted to each weight assists in locking and unlocking the weight from the keel of your decoy for easy deployment and tangle free pack up. By having the weight securely locked onto the keel of each decoy in between uses, damage to paint work is non-existent and there are no lines lying around to encourage tangles or other hassles. Kiss broken elastics and loose sinkers goodbye and enjoy the ease of use of these J weights.
