Product Summary

The Trailer Valet STJW0020 heavy-duty square weld on jack lifts and supports trailers weighing up to 7,000 pounds. This heavy-duty square jack, is ideal for large utility trailers, dump trailers, and car haulers. With a welded-on design, it offers unmatched stability and lifting strength when securing or leveling your trailer for loading, storage, or hitching without the need for bolt-on brackets or removable hardware. Built from solid steel with a rugged square tube design, this jack provides increased structural integrity and lift reliability. Finished with a durable black powder-coated exterior to resist rust and environmental wear, the jack body supports a travel distance of 14in. and an added 15in. drop leg for maximum adjustability and clearance on tall trailer frames. It features a side-wind handle for smooth, ergonomic lifting and lowering of your trailer tongue. Weld-on mounting ensures a permanent, ultra-secure fit on square frame trailers. The jack offers 23.5in. of retracted height and expands to a total 51in., making it ideal for tall loads, loading ramps, and uneven terrain where precise height control is essential. Includes one 7,000 lb. rated weld-on jack with side-wind crank handle and integrated 15in. drop leg extension. Engineered specifically for square steel trailer frames that support weld-based attachment, this jack is a reliable replacement or upgrade for utility, landscape, or equipment trailers that need extra lift performance and structural support. Welds directly to your trailer frame for a permanent, high-strength attachment. No mounting bracket is included or required, streamlining the installation process. Designed to fit square frames up to 5in. tall, this jack provides a clean, low-profile setup and minimizes lateral movement under heavy loads. Professional welding recommended for best results.
