OULEME Trailer Jack Wheel Dock — 12"x12" polypropylene pad, 6" inside diameter fits 6"/8" casters

OULEME Trailer Jack Wheel Dock is a polypropylene jack wheel chock that stabilizes trailer jack casters, prevents sinking on soft ground, and secures your trailer at rest.

Designed for camper owners, boat trailers, and anyone who uses tongue jacks, this wheel dock fits single 6", 8", and double 6" casters and provides a low-profile, durable base to keep your trailer steady. The dock’s 12" x 12" footprint and 6" inside diameter give broad contact with the ground to reduce pressure and prevent the jack wheel from digging in. Built from thickened polypropylene and featuring pre-drilled mounting holes, it combines weather-resistant performance with options for permanent installation or portable use.

How does the OULEME jack wheel dock stop my trailer from sinking on soft surfaces?

The dock increases the surface area under the jack wheel so weight spreads across a wider pad instead of concentrating on a small wheel. That reduces ground penetration on gravel, sand, mud, or turf and helps keep the trailer level when parked. The raised lip holds the caster in the center, so the wheel stays seated even if the ground is uneven.

• 12" x 12" footprint spreads load evenly to limit sinking
• 6" inside diameter cups the jack caster for centered support
• Low 2" height keeps trailer access and clearance simple
• Suitable for single 6", 8", and double 6" caster configurations

Is the material durable enough for repeated outdoor use?

OULEME uses reinforced polypropylene for the dock, selected for impact resistance, weather tolerance, and long-term outdoor performance. The structure is thicker and denser than thinner plastic pads, so it resists cracking under intermittent heavy loads and temperature changes. It’s lightweight for transport but engineered to withstand normal trailer-duty stresses.

• Thickened polypropylene construction resists wear and impact
• UV- and moisture-tolerant for outdoor storage and frequent use
• Won’t corrode or rot like metal or wood alternatives
• Compact, portable design for easy handling and storage

Can I secure the dock permanently to a deck or trailer board?

Yes — the dock comes pre-drilled with holes that accept screws for fixed installation onto boards, floors, or platforms. That makes it simple to create a dedicated mounting spot on a storage platform, boat trailer tongue, or campground deck. For temporary needs, it functions equally well as a freestanding pad that can be positioned and removed in seconds.

• Pre-drilled mounting holes for quick screw-in installation
• Use screws to fix to wood decks, trailer tongues, or platforms
• Removable and reusable when permanent mounting isn’t desired
• Rope handle lets you carry or position the dock easily

What sizes and caster types does this jack wheel dock support?

The OULEME wheel dock is available to fit single 6" casters, 8" casters, and double 6" caster setups, and the interior cup measures about 6" in diameter on the shown model. Measure your jack wheel before ordering to ensure a snug fit. The dock’s generous surface area also helps when casters vary slightly in tread or width.

• Inside diameter approximately 6" on the pictured model
• Options available for single 6", 8", and double 6" caster fits
• Works with common tongue jack wheel sizes on RVs and trailers
• Designed to hold casters centered and stable under load

Who is this for: The OULEME Trailer Jack Wheel Dock is aimed at RV owners, boat trailer operators, campers with pop-up trailers, and anyone who parks on soft or uneven ground and wants a simple, long-lasting way to prevent jack sinking. It’s also useful for shops or storage areas that want a fixed mounting solution to protect jack wheels and keep trailers steady during loading and servicing.
