CURT Boat Trailer Jack 1,200 lb Zinc-Plated with 6-inch Wheel, 11-inch Vertical Travel

CURT 28112 is a zinc-plated marine trailer jack with a 6-inch wheel, 1,200 lb support and lift capacity, and 11 inches of vertical travel for easier boat or utility trailer positioning. This heavy-duty tongue jack is built specifically for trailer owners who need reliable, corrosion-resistant lifting and rolling capability at the waterline or on salty roads. CURT engineered this model with a swivel bracket and pull-pin so the jack stows clear of the trailer while towing, and added a 6" wheel to make coupling, launching, and moving trailers by hand simpler on ramps and driveways.

How much load can this jack handle and what frames does it fit?

The CURT 28112 supports and lifts up to 1,200 pounds, making it well suited for many single-axle boat and utility trailers. It ships with bolt-on hardware sized for secure mounting, and the tube dimensions accommodate a wide range of frame sizes.

• Support and lift capacity: 1,200 lbs.
• Included hardware: 3/8-16 x 4" bolt-on set
• Compatible frame sizes: fits 2" x 2" up to 3" x 5" trailer frames

What are the travel, height, and operation details?

This side-wind jack provides 11 inches of vertical travel and uses a side-wind handle for reliable, controlled raising and lowering. The compact retracted height keeps the jack out of the way during storage or when the trailer is being towed.

• Vertical travel: 11"
• Retracted height: 12.5"; extended height: 23.5"
• Operation: side-wind handle for smooth manual adjustment

How does it resist corrosion in marine environments?

CURT designed this model for repeated exposure to water, salt, and road grime by applying a protective zinc finish to the steel surfaces. The zinc plating reduces the chance of surface rust and helps maintain smooth swivel and lift operation season after season if rinsed and inspected regularly.

• Finish: durable zinc plating for corrosion resistance
• Recommended care: rinse after saltwater exposure and inspect moving parts
• Durability features: solid steel construction with heavy-duty pull-pin

How does the swivel and wheel improve trailer handling?

The integrated swivel bracket lets the jack pivot and lock out of the way for travel, while the 6" wheel provides mobility when positioning or coupling a trailer on slopes or uneven surfaces. A heavy-duty pull-pin secures the jack in both stowed and deployed positions for dependable use.

• Swivel design: swings up and clear of the trailer while towing
• Wheel diameter: 6" for easier rolling on ramps and yards
• Locking mechanism: heavy-duty pull-pin for secure stow and use

Who is this for? The CURT 28112 is aimed at boaters, weekend campers, and utility-trailer owners who need a corrosion-resistant, easy-to-operate tongue jack that both lifts and rolls. If you regularly launch or retrieve a trailer, launch from ramps, or live where salt and moisture are concerns, this jack balances mobility, strength, and rugged construction to simplify trailer hookup and storage. It’s a practical upgrade for single-axle trailers that use receiver-style mounting and require dependable, hardware-mounted stability.
