Upgrade the rudder control knob on your Predator PDL with this trucker-style steering knob. Controlling your kayak with this knob required less effort and less stress on your fingers, letting you stay out on the water longer. This steering knob also features a screw-down locking mechanism so you can lock your rudder in place to track straight, drift, or hold a turn without using your hands. Fits all Predator PDL models.
