GARTOWEE 5000 lb A-Frame Trailer Jack — 15in Vertical Travel, 10in Adjustable Drop Leg, Top-Wind Heavy-Duty

The GARTOWEE 5000 lbs A-frame Trailer Jack is a heavy-duty top-wind jack with 15 inches of vertical travel and a 10-inch adjustable drop leg built to lift and stabilize utility, yacht, and camper trailers.

This jack combines a compact retracted profile with long extension range and rugged materials so you can raise, lower, and support trailers reliably. Constructed from high-strength steel and finished with a protective black coating, the unit is designed for repeated use on the road, at the marina, or at the campsite. Its top-wind crank gives controlled lifting while the adjustable drop leg lets you fine-tune height without overextending the inner tube.

How much weight can this jack safely handle?

The GARTOWEE jack is rated for a 5000-pound lifting capacity, suitable for many single-axle and light tandem-axle trailers. Ratings apply to vertical load capacity at the jack, not total trailer weight distribution, so always consider axle loads and trailer balance when lifting.

• Maximum static load: 5000 lbs
• Designed for a-frame and tongue-mounted applications
• Best used for utility trailers, small yachts, and many campers
• Not intended as the sole support for prolonged vehicle servicing

What are the size and travel specifications?

The jack offers 15 inches of vertical travel via the top-wind mechanism and an additional 10-inch adjustable drop leg for extra clearance. Its overall retracted height is 20 inches and full extension reaches approximately 45 inches, giving wide compatibility with different coupler heights.

• Retracted height: 20 inches
• Vertical travel: 15 inches
• Adjustable drop leg: up to 10 inches
• Extended height: roughly 45 inches for high-clearance needs

How durable is the finish and construction for outdoor use?

The body is made from high-strength steel with a protective black coating to resist corrosion from water, dirt, and road salt. That finish helps the jack withstand marina and roadside environments, though regular cleaning and inspection will extend service life.

• High-strength steel construction for structural durability
• Protective black coating for corrosion resistance
• Sealed fasteners and welds to reduce moisture intrusion
• Recommended periodic lubrication and rinse after salt exposure

How easy is it to operate and install?

The top-wind handle is ergonomically shaped for a secure grip and smooth turning, allowing single-person operation for most lifting tasks. Mounting follows common A-frame jack patterns, and the adjustable drop leg reduces manual cranking when setting trailer height.

• Top-wind crank provides controlled lifting and lowering
• Ergonomic handle reduces hand fatigue during operation
• Standard bolt pattern compatible with most A-frame mounts
• Drop leg lets you fine-tune height with less effort

Who is this for: The GARTOWEE 5000 lb A-frame Trailer Jack is aimed at trailer owners who want a robust, versatile lifting solution—boaters, campers, and utility trailer users who need dependable support at the dock, campsite, or worksite. It’s well suited for anyone replacing a worn jack or upgrading to a higher-capacity, corrosion-resistant unit; professional installers and DIY owners alike will appreciate its build quality and practical travel range. For safe use, pair the jack with proper wheel chocks and secondary stands when working under the trailer or leaving it supported for extended periods.
