An industrial wheel chock is a wedge-shaped block placed under a vehicle tire to prevent the vehicle from rolling, used at loading docks, fleet yards, RV parks, aviation FBOs, and any site where a parked vehicle's parking brake alone is insufficient to hold the load. Industrial chocks are not the same as the spinning-wheel cursor on a Mac, the Meals on Wheels program, or any other unrelated meaning of the word "wheel" -- this guide covers the load-securing wedge product class only. OSHA, DOT, and FAA each have specific chocking requirements that govern when and how to use them.
What Is an Industrial Wheel Chock?
An industrial wheel chock is a load-securing safety device, typically rubber, urethane, or aluminum, with a wedge profile that fits against the tire tread and the ground simultaneously. Two chocks placed front and rear of one tire (or one chock placed downhill of one tire on a slope) lock the vehicle in position. The U.S. Occupational Safety and Health Administration's general industry standard at 29 CFR 1910.178(k)(1) requires that "the brakes of highway trucks shall be set and wheel chocks placed under the rear wheels to prevent the trucks from rolling while they are boarded with powered industrial trucks."
That regulation -- one sentence -- governs roughly half of all industrial chock use in the United States. Loading-dock operations cannot legally proceed without chocks (or an equivalent dock-lock system) under the rear tires of a parked truck. The same logic applies at fleet yards, distribution centers, and any site where a forklift or pallet jack enters the trailer.
What Are the Five Main Types of Industrial Wheel Chocks?
Industrial chocks split into five product families. Each has a use case, a typical material, and a price band.
Rubber Wheel Chocks
The dominant product class for general industrial use. Recycled or virgin rubber, durometer 70 to 80 Shore A, weight 5 to 25 pounds per chock depending on size. Rubber grips wet, oily, and snow-covered pavement better than any other material. Standard for loading docks, fleet yards, and most truck-and-trailer operations. The 5400 monthly U.S. searches for "rubber wheel chocks" reflect the category's dominance in industrial buyer searches.
Urethane Wheel Chocks
Higher-density alternative to rubber. Better cold-weather performance (less stiffening at sub-freezing temperatures) and longer service life. Typical weight 8 to 18 pounds. Specified at high-cycle docks where chocks see hundreds of placements per week. Cost premium of 30 to 60 percent over rubber.
Aluminum Wheel Chocks
Lightweight metal chocks for aviation and high-end fleet use. Weight 3 to 8 pounds with rope handles for quick placement. Bright red or orange anodized finish for visibility. Used where a heavy chock would damage the surface (polished hangar floors, marble entry pads) or where the operator must move the chock dozens of times per shift.
RV Wheel Chocks
Consumer-recreational variant designed for stabilizing parked RVs against side-to-side roll between dual tires (a stabilization function, not a stopping function). Plastic, urethane, or aluminum. Typically purchased in pairs and X-pattern stabilizers. Edge of the industrial category but tracked here because the product class shares vocabulary and standards with industrial chocks.
Aviation Wheel Chocks
Specialty chocks designed for aircraft tires, typically with a contoured profile that matches aircraft tire curvature and a rope-handle for ground-handler use. Aluminum, urethane, or wood construction. The Federal Aviation Administration's FAR 91.13 (careless or reckless operation) and FAA Advisory Circular AC 150/5210-25 cover ground-handling equipment guidance for general aviation and commercial aircraft.
What Materials Are Used to Make Wheel Chocks?
Material selection drives weight, friction, and cost. The four dominant materials:
| Material | Friction Coefficient (typical) | Weight (15-inch chock) | Cold-Weather Performance | Service Life |
|---|---|---|---|---|
| Rubber (recycled) | 0.7 to 0.9 | 12 to 18 lbs | Stiffens below 20 F | 5 to 10 years |
| Urethane | 0.8 to 0.95 | 10 to 16 lbs | Holds flexibility to -40 F | 10 to 15 years |
| Aluminum (anodized) | 0.4 to 0.6 (depends on tread) | 4 to 8 lbs | Unaffected | 20 to 30 years |
| Wood (oak, maple) | 0.5 to 0.7 | 8 to 14 lbs | Unaffected but absorbs water | 2 to 5 years |
When Are Wheel Chocks Required by Regulation?
Three federal regulations govern industrial chock use. Each one applies at different sites.
OSHA 29 CFR 1910.178(k) -- Loading Docks
Highway trucks parked at a loading dock with powered industrial trucks (forklifts) entering the trailer must have brakes set AND wheel chocks placed at the rear wheels. The regulation applies at any general-industry workplace, which covers warehouses, distribution centers, manufacturing plants, and retail receiving docks. Cojo regularly sees OSHA citations on this rule during dock-safety audits.
DOT 49 CFR 392.20 -- Commercial Motor Vehicle Operators
A commercial motor vehicle in motion must have its brakes set when not attended. Chocks are not explicitly required by this rule, but they are the standard means of compliance when a driver leaves a parked CMV on a grade. See our OSHA wheel chock requirements guide for complete regulatory cross-reference.
FAA Advisory Circular 150/5210-25 -- Aviation Ground Handling
Aircraft parked on ramps and at aircraft FBOs require chocks at the main landing gear when the parking brake alone is insufficient (long-term parking, high-wind conditions, or when refueling). The chocks must be in place before the engine is shut down per most operator policies.
How Do Wheel Chocks Compare to Wheel Stops?
A wheel chock is a movable wedge placed under-tire to lock a vehicle in position temporarily. A wheel stop is an anchored barrier set at the head of a parking stall to stop the vehicle's forward motion at a fixed point. The two products share vocabulary and visual similarity but solve different problems. See our wheel stops buyer's guide for the full wheel-stop product taxonomy. Quick comparison:
| Feature | Wheel Chock | Wheel Stop |
|---|---|---|
| Anchored | No (movable) | Yes (anchored at stall head) |
| Use case | Loading dock, parking-brake aid, slope hold | Parking stall depth control |
| Material | Rubber, urethane, aluminum | Concrete, rubber, recycled plastic |
| Position | Under the tire | At the front of the parking stall |
| Regulatory driver | OSHA / DOT / FAA | ADA, local code |
What Does an Industrial Wheel Chock Cost in 2026?
Industry Baseline Range
| Spec | Per-Unit Range |
|---|---|
| Rubber chock, 8 to 12 inch, 70-80 durometer | $20 to $50 |
| Rubber chock, heavy-duty 15-inch+ | $40 to $90 |
| Urethane chock, mid-size | $40 to $100 |
| Urethane chock, heavy-duty | $80 to $180 |
| Aluminum chock, 8 to 10 inch, anodized | $90 to $250 |
| Aviation aluminum, rope-handle | $200 to $500 |
| RV chock pair (stabilizer) | $25 to $80 |
Current Market Reality
Recycled-rubber chock pricing has stayed relatively stable through 2025 and into 2026 because the recycled tire feedstock has not seen the volatility of virgin synthetic rubber. Urethane and aluminum chocks track petroleum and bauxite commodity markets respectively. Bulk pricing tiers (50+ units) typically deliver 15 to 25 percent discount over single-unit pricing.
Where Has Cojo Specified Wheel Chocks?
Cojo serves industrial dock and fleet-yard sites primarily as a paving and parking-products contractor; chock supply is part of dock-safety package recommendations rather than a standalone product line. In March 2026 Cojo's lead estimator (NICET Level III, OSHA-30 certified) specified 24 heavy-duty rubber chocks for a Hillsboro warehouse expansion -- 12 dock positions, 2 chocks per position. The site needed chocks rated for Class 8 truck and trailer rears under forklift loading, which placed the spec in the 15-inch-plus rubber category. Bulk procurement through Cojo's industrial-supply channel saved roughly 18 percent over single-unit pricing.
