ROBLOck Solid Rubber Wheel Chocks — 2-Pack Black 8.6" x 3.7" x 4.7" for Trailers, RVs, Cars — Heavy-Duty, All-Weather Grip

ROBLOck Solid Rubber Wheel Chocks are heavy-duty, all-weather chocks designed to secure trailers, RVs, cars and ATVs up to a gross vehicle weight of 4 tons.

These molded rubber wheel chocks combine a compact footprint with deep-grip surfaces and a built-in handle, delivering a portable, durable way to prevent vehicle movement during parking, maintenance or loading. Each chock measures 8.6" L x 3.7" W x 4.7" H and comes as a two-piece set engineered for traction on pavement, gravel and other common surfaces. The oil-resistant rubber compound resists wear and stays grippy in rain, mud and cold weather.

How do these chocks keep my trailer or RV from rolling?

The chocks feature angled faces and high-friction tread that bite into tire rubber and the ground to resist both forward and backward movement. Their weight and shape distribute force across the wheel contact patch so the vehicle rests securely without slipping.

• Angled profile designed to sit firmly against tire curvature
• Deep, non-slip tread pattern for traction on wet or oily surfaces
• Solid rubber mass provides stable resistance to rolling forces
• Works on both tires and wheel hubs for added versatility

What makes ROBLOck chocks suitable for outdoor, all-weather use?

Manufactured from a resilient rubber compound, these chocks are formulated to resist cracking, hardening or losing grip in temperature extremes. The material is oil-resistant and water-shedding so it maintains traction after exposure to fuel, motor oils or rain.

• Oil-resistant rubber keeps grip when exposed to automotive fluids
• Weather-tough construction resists cold-induced brittleness
• Non-absorbent surface reduces freezing and water retention
• UV-stable finish helps prevent surface degradation over time

How easy is it to carry, store and use these chocks?

Each chock includes an integrated rubber handle molded into the body so you can move them with one hand and tuck them away when not in use. Their compact dimensions make them simple to stow in a vehicle compartment, onboard storage bay or garage shelf.

• Built-in handle for quick placement and retrieval
• Lightweight enough for single-person use yet sturdy in service
• Stackable shape saves space when stored as a pair
• Ready-to-use right from the box — no assembly required

What types of vehicles and tasks are these wheel chocks best for?

Rated for vehicles up to a G.V.W. of 4 tons, these chocks are ideal for smaller trailers, personal RVs, cars, light trucks, ATVs and utility trailers. They’re also handy for short-term maintenance stops, loading/unloading and securing parked equipment.
