The Trailer Valet JX5 (Swivel Pipe Mount) is a manual trailer jack that has the versatility to be powered using any standard 18-20V drill and a Trailer Valet Drill Attachment. This product was created with the marine consumer in mind, to make hitching and adjusting quick and convenient. As most electric jacks are not suitable for marine or heavy trailer setting and standard and manual swivel jacks can take extensive time and effort to use, the Trailer Valet JX5 offers a reliable, versatile solution between the two. The unit has a capacity of 5,000 lbs (900 kg), ideal for most trailers types with 8" of extra space to install. Use included hand crank or combine with Trailer Valet Drill Attachment (TVDA) and (18-24v) drill to adjust the height up and down.
