The powerful REESE Towpower Trailer Jack fits tongues 3” to 5” and helps effectively raise and lower trailers with a capacity up to 1,000 lbs. Operating with a 1:1 gear ratio, the side-winding handle with a wire-grip knob allows for fast and smooth usage while a heavy-duty swivel mechanism and pull-pin release make it easy to access the device when you need it, and store it away when you don’t. For added mobility, this jack includes 6” wheel that glides easily and lowers the friction to help you move a trailer into position with minimal effort.
