J and K Tackle in-line weights are hand-poured, hand-painted and feature roller swivels with duo-lock snaps. J and K Tackle in-line weights attach on the top for true horizontal travel through the water. They are available in 1/2oz., 3/4 oz., 1 oz., and 1.5 oz. Originally designed to be used with our in-line harnesses, they can also be used with regular length crawler harnesses or to take shallow running crankbaits down to depth.
