ROBLO­CK Rubber Wheel Chocks 4-Pack (Black) Heavy-Duty Non-Slip with Reflective Tape & 30" Nylon Rope for Trailers, RVs, Cars

ROBLOck heavy-duty rubber wheel chocks—a set of four non-slip wheel blocks with reflective tape and a 30" nylon rope to keep cars, trailers, RVs and trucks securely stopped.

These rubber wheel chocks are built for frequent use around vehicles of many sizes. Molded from robust, oil- and weather-resistant rubber, each wedge offers a deep tread and three-sided grip to reduce movement on driveways, gravel, ramps and campsites. Bright yellow reflective stripes and a long connecting rope make them easier to see and position at night or when working with larger trailers and trucks.

How do these chocks make parking or towing safer?

The chocks create a solid physical barrier behind or in front of tires to prevent unintended rolling when parked or hooked to a hitch. Their textured edges bite into surfaces while the heavy rubber body resists sliding under load.

• Three-sided grip design increases contact with tire and ground for stability.
• Reflective tape improves visibility during low-light setups.
• Rubber construction resists oil, weather, and abrasion for consistent performance.

Will these fit my trailer, RV or truck tires?

Each chock measures approximately 7.8" x 4.1" x 3.9" and weighs 6.6 pounds, which suits most passenger vehicles, small to medium trailers, RVs and light trucks. The wedge profile supports a range of tire diameters while maintaining contact to stop movement.

• Dimensions sized for common car and trailer tires without lifting the vehicle.
• 6.6 lb weight for easy positioning yet heavy enough to stay put under load.
• Works for cars, campers, vans, boats on trailers, and utility trailers.

How does the 30" nylon rope and reflective tape help in practical use?

The long nylon rope keeps chocks paired and easy to retrieve when placed around large vehicles, while reflective stripes increase visibility during night stops and roadside setup. Together they reduce fumbling and improve safety when parking on dim campsites or busy service areas.

• 30" rope connects chock pairs for quick placement and retrieval.
• Yellow reflective stripes alert others to the chocks’ location in low light.
• Rope helps hang or stow chocks on hooks or in storage compartments.

How durable and maintenance-free are these rubber wheel blocks?

Made from heavy-duty rubber, the chocks tolerate oil, moisture and temperature changes better than many plastic alternatives, holding shape and grip over repeated use. Clean with water and mild detergent to remove grime and extend service life.

• Oil- and weather-resistant rubber stays reliable in outdoor conditions.
• Anti-slip edges maintain traction on asphalt, gravel, and concrete.
• Simple rinsing keeps surfaces free of debris for maximum grip.

Who is this for: These ROBLOck wheel chocks are intended for vehicle owners and operators who need dependable, reusable blocking for parking, maintenance, towing and storage. They’re a practical choice for RVers, trailer owners, small-fleet operators, service technicians and homeowners who want a visible, weather-resistant solution to prevent rolling. If you frequently work with trailers, park on inclines, or need a durable chock that won’t crack like plastic alternatives, this four-pack offers a balance of visibility, weight and grip for everyday and heavy-duty use.
