The Top-Wind Jack with Swivel Mount from Buyers Products is an easy to use jack for many lighter duty trailers. The swivel mount welds on to the trailer tongue to let you quickly swing the jack up for traveling and back down for use. It is ideal for trailer parking. The crank is on the top for easy operation using an ergonomic handle. The black powder-coated finish and zinc-plated base and crank help it withstand whatever weather comes its way. Choose from two travels -- 10 in. or 15 in. -- from the mounting bracket to the top of the jack, excluding the handle. Both models have a tongue weight capacity of 2,000 lb. The bolt-on mounting assembly is sold separately.
