The PR500 Plate Retractor Kit adds versatility and convenience to any Smart Tabs installation by giving boaters the ability to instantly switch between normal trim tab operation and a fully retracted position—without tools. The easy-to-use lever system allows Smart Tabs to function normally when the handle is in the down position and retracts the trim plates completely when the handle is moved to the up position.
