OPENROAD 5000 lb A-Frame Trailer Jack 15-inch Top-Wind Vertical Travel, Silver — Foot Plate, Heavy-Duty

OPENROAD 5000 lbs A-frame trailer jack is a heavy-duty, top-wind vertical tongue jack that lifts trailers, RVs and boat tongues up to 15" with a sturdy foot plate for stable support.

This high-capacity A-frame jack from OPENROAD is built to handle demanding towing tasks while remaining simple to operate. Made from heavy-gauge steel and finished with corrosion-resistant electroplating, it combines a manual top-wind crank with a lubricated gear system for smooth movement. The jack’s broad lifting range and integrated foot plate deliver reliable, stationary support for trailers, campers, and small boat lifts without requiring power.

How much weight can this jack safely support?

The OPENROAD A-frame jack is rated for a 5,000 lb trailer tongue load, meaning it is engineered to support the tongue weight portion of medium- to large-size trailers. This rating applies to vertical load on the jack when properly mounted to the trailer A-frame.

• Rated 5,000 lb tongue weight capacity
• Designed for A-frame tongue mounting standards
• Suitable for trailers, RVs, campers and small boat towing setups

How far does the jack lift and how smooth is the operation?

The jack offers a top-wind vertical travel with a 15" maximum lifting height and a useful travel range that accommodates typical hitching and leveling needs. A lubricated gear system and ergonomic crank handle reduce effort and minimize binding for predictable, repeatable lifts.

• 15" maximum top-wind lift travel
• Adjustable travel span for fine leveling control
• Lubricated gears and ergonomic crank for smooth turning

What materials and finishes protect the jack from corrosion and wear?

OPENROAD builds the jack from heavy-duty A3 steel for strength and stiffness under load, then applies an electroplated surface finish to improve corrosion resistance. These choices help the jack withstand road exposure and outdoor storage when basic maintenance is performed.

• Heavy-gauge A3 steel construction for structural rigidity
• Electroplated surface finish to resist rust and weathering
• Sealed or lubricated gear components to limit wear

How versatile is the jack for different towing setups?

Because it mounts to an A-frame and uses a manual top-wind crank, this jack adapts to a wide range of trailers and small boat applications without needing electrical power. The included foot plate increases ground contact and stability, making it practical for temporary parked support or hitching operations.

• Fits A-frame trailer tongues on campers, RVs, and utility trailers
• Manual operation—no batteries or wiring required
• Foot plate provides steadier base on varied ground surfaces

Who is this for: The OPENROAD 5000 lbs A-frame trailer jack suits owners of medium to heavy trailers, RVs, and boats who need a robust, manual lifting solution for hitching, leveling and parked support. It’s a practical pick for DIYers, weekend boaters, tow professionals, and anyone wanting a corrosion-resistant, smooth-operating jack that doesn’t depend on electric power. Regular lubrication and correct mounting ensure long-term performance and safe use.
