NBJINGYI 5000 lb Trailer Jack - 10" Lift Swivel Pipe/Square Tube Mount, Side-Wind Handle

The NBJINGYI Heavy Duty 5000LB Trailer Jack is a robust, swivel-mounted pipe jack that gives trailers and RVs stable support and up to 10 inches of vertical adjustment with a lock pin and side-wind handle.

Built for demanding towing and storage conditions, this trailer jack combines a high support rating, corrosion-resistant finishes, and a welded mounting bracket for permanent installation. Its 360° rotating bracket tucks the leg neatly out of the way when towing, while the side-wind handle and textured grip make raising or lowering a trailer straightforward. The jack is finished in a durable black powder coat with zinc-plated components to resist road and weather exposure.
