CURT A-Frame Trailer Jack 5,000 lb Support, 14" Travel — Top-Wind Handle, Corrosion-Resistant

The CURT 28250 is a heavy-duty A-frame trailer jack that provides up to 5,000 lb of support, 3,000 lb of lift, and 14 inches of vertical travel with a top-wind handle for reliable trailer positioning.

Built for trailers with an A-frame tongue, the CURT 28250 combines robust capacity and corrosion-resistant finishes to stand up to frequent towing and outdoor exposure. It installs by bolting or welding to the frame, retracts completely for travel clearance, and uses a top-wind mechanism for controlled raising and lowering. This jack is intended to make hitching, leveling and storage easier while resisting rust and wear from road conditions.

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

The CURT 28250 is engineered to offer a 5,000 lb static support rating and a 3,000 lb lift capacity. The support rating indicates the maximum tongue weight the jack can bear while the lift rating indicates the safe load the jack can raise when cranking.

• 5,000 lb support capacity for secure tongue bearing
• 3,000 lb lift capacity for raising couplers and jacks stands
• Designed for A-frame trailer tongues and receiver-style setups

What range of movement and travel height does it offer?

This model provides approximately 14 inches of vertical travel so you can level or lower your trailer to match a hitch ball or parking surface. It retracts fully to minimize protrusion while towing and extends far enough for loading, connecting, or storing your trailer.

• 14-1/8 inches of vertical movement for hookup flexibility
• 10-3/8-inch retracted height for safe towing clearance
• 24-1/2-inch extended height for convenient lifting reach

How does the top-wind handle and construction impact usability?

The top-wind handle places the crank where it’s easy to grip and operate from above, giving you better leverage while raising or lowering the tongue. The handle includes an integrated grip for more comfortable and predictable operation during repeated use.

• Top-wind design for ergonomic cranking and precise control
• Integrated grip on handle for comfortable operation
• Simple manual mechanism with straightforward maintenance needs

Will this jack resist corrosion and how is it attached?

CURT finished this jack with a black powder coat plus zinc-plated components to reduce corrosion from water, road salt, and grime. The A-frame design can be secured by bolting or welding to the trailer tongue, giving you installation options to match your trailer’s construction.

• Durable black powder coat and zinc plating for added rust resistance
• Can be bolted into place or welded directly onto the tongue (hardware not included)
• Made for long-term outdoor exposure and varied towing environments

Who is this for: The CURT 28250 suits owners of A-frame trailers who need a rugged, no-frills jack for regular towing, seasonal storage, or loading tasks. It’s a good match for boat trailers, utility trailers, small campers and other receiver-style trailers where a fixed A-frame jack is preferred over a swivel unit. If you want a high-capacity, corrosion-resistant jack with simple top-wind operation and full retraction for travel, this model is designed to deliver those features reliably.
