Whether you need a strong dump trailer jack Monday through Friday or you're heading out with the boat on Saturdays, you can lift or lower your trailer in a matter of seconds with a 20-24V cordless drill.The JX7-S comes with a detachable hand crank, drill attachment, mount bracket hardware, and footplate.Easy and Fast OperationThe JX7-S is an elbow saver that was built for speed. Forget waiting on slow electric trailer jacks or wearing out your arm with only a hand crank. The JX7-S comes with both a manual crank and drill chuck for use with any standard 20-24V cordless drill, so raising or lowering your jack has never been easier. Bringing the jack up or down is as simple as connecting the drill attachment and squeezing the trigger on your cordless drill.Unmatched FunctionalityNo details were overlooked in designing the JX7-S to be the best heavy-duty, side crank trailer jack available. The JX7-S bolts onto your trailer frame with a fixed bracket for an easy mount. Each bracket has 6.4 inches of space between the top and bottom holes so you're able to get the perfect fit jack with no welding. Material: Steel.
