CURT A-Frame Trailer Jack 5,000 lb Support, 14 in Travel — Black Top-Wind, Bolt/Weld Mount

CURT 28250 is a heavy-duty A-frame trailer jack that provides up to 5,000 lb of static support and 14 inches of vertical travel with a comfortable top-wind handle.

Built for trailers with A-frame tongues, the CURT 28250 combines robust capacity and corrosion-resistant finishes to make hitching, leveling and storing your trailer simpler and more reliable. It mounts either by bolting or welding, retracts fully for towing clearance and uses a top-wind crank for controlled raising and lowering. Designed to stand up to road salt, water and dirt, this jack is meant to extend the service life of your trailer and reduce hassle at the hitch.

How much weight can this A-frame jack safely support?

The CURT 28250 is engineered to hold a maximum static support weight of 5,000 lb and a lift (operational) capacity of 3,000 lb. These ratings mean it can support larger utility, boat or equipment trailers when parked or during coupling operations. Always confirm your trailer’s tongue weight and distribute loads properly before relying on any jack.

• Support capacity: 5,000 lb (static)
• Lift capacity: 3,000 lb (while cranking)
• Check tongue weight relative to jack rating for safe use

What is the travel range and retracted height?

This jack offers 14-1/8 inches of vertical travel, giving plenty of range to raise and lower couplers for hitching and leveling. When fully retracted it sits low for towing clearance and then extends to its full height for setup. The travel range covers common trailer configurations from low-loaders to taller tongue heights.

• Vertical travel: 14-1/8"
• Retracted height: approximately 10-3/8" for towing clearance
• Extended height: approximately 24-1/2" for hitching

How is the jack operated and installed?

Operation uses a top-wind handle with an integrated grip for smoother, more controlled cranking; the top-wind design keeps the handle accessible and convenient. Installation is flexible — you can bolt it on using your preferred hardware or weld it directly to the tongue if a permanent mount is desired. The tube design retracts fully to avoid interfering with travel when the trailer is in motion.

• Top-wind handle with comfort grip for easier cranking
• Mount options: bolt-on or welded (fasteners not included)
• Fully retractable for secure towing clearance

How does the finish hold up to weather and road use?

To resist corrosion from moisture, salt and grime, this jack combines a black powder coat with zinc-plated components for long-term protection. That finish helps minimize surface rust and keeps moving parts functioning reliably with routine maintenance. Wiping, occasional lubrication of the screw and storing the trailer under cover when possible will extend service life even further.

• Durable black powder coat for exterior protection
• Zinc-plated parts reduce corrosion on critical contacts
• Simple upkeep: clean and lubricate screw periodically

Who this is for: The CURT 28250 is suited for owners of A-frame trailers—boat trailers, utility rigs, livestock trailers and similar—who need a rugged, non-swivel jack with high static support and reliable retraction. Choose this jack if you want sturdy lifting capacity, a top-wind crank for controlled operation, and a finish built to withstand road and waterfront conditions. If you require a swing-away or swivel feature for storage, consider CURT swivel models instead; otherwise, the 28250 is a practical, long-lasting solution for secure trailer support.
