Vervelette Wheel Chocks for RV & Trailer — 4-Pack Fluorescent Rubber with 8mm Sawtooth Grip

Vervelette Wheel Chocks RV Trailer are heavy-duty rubber chocks designed to lock wheels securely with 8mm sawtooth grips, reflective warning accents, and a durable rope—sold as two pairs (four total).

When parking an RV, trailer, or tow vehicle on uneven or slippery surfaces, dependable wheel chocks reduce unwanted movement and improve safety during loading, maintenance, or overnight stops. These Vervelette chocks combine dense rubber construction with deep teeth and high-visibility features so you get reliable bite, strong load capacity, and easier night-time detection without bulky metal parts.

How do these chocks keep my RV from rolling?

The chocks use a sawtooth surface at least 8mm deep and a high-density rubber compound to grip tire treads and the ground. Their triangular geometry and textured sides create a wedge that resists displacement under static and sudden loads, tested to support heavy weight and steep angles.

• 8.2" x 4.4" x 3.6" triangular profile for firm wheel engagement
• High-density rubber with friction coefficient ≥0.85 for better grip
• 15,000 lb static load-bearing capacity and resistance to 30° slope impact
• Sawtooth teeth for mechanical bite into asphalt, dirt, and snow

Will they work at night or in low visibility?

Vervelette chocks include a triple-warning system: reflective strips, a bright fluorescent color, and a long rope to improve visibility from any angle. These features reduce the chance of accidental impact by other drivers or pedestrians in low-light situations.

• Reflective bands wrap around each chock for 360° visibility
• 39.37" rope connects chocks and helps locate them quickly
• Fluorescent color makes chocks easier to spot during dusk or dawn

Are these compatible with my RV or trailer tires?

Designed to fit a broad range of vehicles, the chock triangle height of 4.72" accommodates tire diameters commonly found on North American RVs. They suit most motorhomes and trailers as well as cars, trucks, SUVs, ATVs, boats and some small aircraft ground operations.

• Triangle height: 4.72" compatible with 16"–22.5" tires
• Works with 98% of mainstream A/B/C class RV models and trailers
• Appropriate for passenger vehicles, light trucks, and off-road rigs

How do these chocks perform on different terrains and in bad weather?

The combination of deep teeth and flexible rubber makes these chocks adaptable across sand, mud, snow and icy surfaces. The material retains flexibility at very low temperatures to maintain contact and resist freezing, while the tooth design forms a mechanical grip or vacuum effect depending on ground type.

• 8mm tooth depth for mechanical bite in sand and soft soils
• Elastic rubber stays flexible down to -40°C to avoid cracking
• Vacuum adsorption effect on mud and anti-freeze behavior on snow and ice

Who is this for? Travelers, weekend campers, full-time RVers, and tradespeople who need portable, dependable wheel security will appreciate the Vervelette Wheel Chocks. They suit anyone who wants compact storage, quick deployment, and strong all-weather performance—useful for roadside stops, campgrounds, boat ramps, or driveway maintenance. Each purchase includes two pairs (four chocks) with a reflective rope for paired-wheel use and tidy storage, making them a practical addition to any vehicle emergency kit or seasonal gear bag.
