AR-PRO Jack Wheel Chock Stabilizer 6" Single Wheel — Heavy-Duty Nitrile Rubber, Drainage

This rugged wheel chock is engineered to give caravan, trailer and camper jack casters a stable, long-lasting base on soft or uneven ground. Molded from premium nitrile rubber in one piece, the AR-PRO chock spreads weight, resists oil and abrasion, and includes a drainage hole to avoid water pooling. It’s tailored for 6" (150mm) single swivel caster wheels and sized to stow easily in your vehicle.

How does this chock stop a jack wheel from sinking into soft ground?

The chock increases the surface area under the jack wheel so the load is distributed instead of concentrated. That prevents the wheel from digging into mud, sand, or gravel and keeps the trailer level when parked.

• Molded nitrile rubber construction resists deformation under load.
• Flat, wide base spreads weight to reduce pressure on soil.
• Raised lip secures the wheel and prevents lateral slipping.

Will this fit my trailer’s 6" single swivel caster jack wheel?

The AR-PRO chock is designed specifically for 6" (150mm) single swivel caster wheels but also fits many similar solid wheels. Check the caster diameter before ordering to ensure a snug fit and optimal performance.

• Recommended for 6" (150mm) trailer swivel caster single wheels.
• Works with RV trailers, boat trailers, pop-up campers and tent trailers.
• Compact dimensions (6.6" x 5" x 1.38") for convenient storage and compatibility.

How does the design extend the life of my jack wheel?

By keeping the wheel off corrosive or contaminating surfaces and shedding water, the chock reduces wear, prevents rust and blocks ingress of mud and oil. This lowers maintenance needs and helps preserve bearings and wheel finishes.

• Drainage hole prevents standing water and reduces rust risk.
• Rubber barrier protects wheels from grit, oil and corrosive surfaces.
• Heavy-duty material resists cracking, slicing and UV exposure under normal use.

How easy is it to handle and store this chock when not in use?

The unit is lightweight enough to carry by hand but heavy-duty in performance. Its low-profile size fits neatly in a vehicle compartment or camping kit so you can deploy it quickly when you set up camp or park your trailer.

• Compact dimensions for quick stowage in trunks or tool compartments.
• Single-piece molding eliminates loose parts and simplifies handling.
• Durable construction means it stays serviceable season after season.
