OULEME Trailer Jack Wheel Dock — 6" Caster Polypropylene Base with Rope Handle & Mounting Holes

OULEME Trailer Jack Wheel Dock is a heavy-duty polypropylene base that stops jack casters from sinking or rolling, giving your trailer stable support on soft or uneven ground.

Whether you park an RV, boat trailer, pop-up camper or tent trailer, a reliable jack wheel dock keeps your tongue jack and caster from digging in or shifting. This model from OULEME is molded from dense polypropylene, sized to fit common caster diameters, and includes a rope handle and pre-drilled holes so you can carry, position, or fasten it where needed. Below are practical answers to the most common buyer questions about fit, durability, installation and everyday use.

What sizes and caster types does the jack wheel dock fit?

The OULEME dock is available for single 6" casters, single 8" casters, and a double 6" caster configuration. The listed internal diameter measures about 6" on the shown model; choose the variant that matches your jack wheel diameter for a snug fit.

• Inside diameter: roughly 6" for the pictured single-wheel version.
• Available options: single 6", single 8", or double 6" caster layouts.
• Check your caster measurement across the widest point before ordering.

How does this dock prevent sinking and improve trailer stability?

Built with increased density and thicker walls of polypropylene, the dock spreads load over a wider surface area to reduce ground pressure. That prevents the jack wheel from digging into soft soil or sand and helps maintain a level, secure trailer while loading, unloading or storing.

• Large flat footprint reduces pressure on soft surfaces.
• Durable polypropylene resists deformation under load.
• Rope handle lets you place or remove the dock without kneeling in mud or gravel.

Can I secure the dock to a platform or wooden board?

Yes — the base includes pre-drilled holes so you can fasten the dock with screws to decking, ramps or mounting boards. Securing it prevents shifting during repeated use and is useful when integrating the dock into a storage station or trailer step platform.

• Pre-drilled holes accept common screw sizes for wood or composite surfaces.
• Fastening makes the dock a semi-permanent support point on ramps or docks.
• Screws or bolts should match the mounting surface and expected load.

How tough is the material, and how long will it last outdoors?

The OULEME dock is molded from robust polypropylene formulated for higher density and thickness, so it resists cracking, warping, and most fading from normal outdoor use. Proper storage when not in use and avoiding prolonged UV exposure will extend service life.

• High-density polypropylene resists impact and wear.
• Thicker walls add stiffness under weight and reduce flexing.
• Store under cover in winter to limit long-term UV exposure.

Who is this for: The OULEME Trailer Jack Wheel Dock suits RV owners, boat and camper enthusiasts, DIY trailer builders and anyone who parks on grass, gravel, sand or soft soil and needs a simple, durable solution to stop jack casters from sinking or rolling. Pick the size matching your caster, fasten it if you want a permanent fixture, and use the rope handle to move it quickly between vehicles or storage locations.
