CircleRoad Trailer Jack Block 1-Pack, 11.22in Square 4in High — Heavy-Duty UV-Resistant Stabilizer

CircleRoad Trailer Jack Block is a single heavy-duty, UV-resistant camper jack pad designed to stabilize trailer tongue jacks and prevent sinking or wobble on soft or uneven ground.

When you park a trailer or RV, the jack foot often bears the full weight on turf, gravel, asphalt, or packed dirt. This single 1-pack CircleRoad jack pad provides a wide, stable base that spreads load, resists weathering, and simplifies setup so your camper stays level and secure. Built from reinforced plastic and tested for strength, it’s an easy add-on to any jack, post foot, stabilizer or scissor jack.

How does the CircleRoad jack block improve stability?

The jack block increases footprint area beneath the jack foot, reducing pressure on the ground and preventing sinking into soft surfaces. Its solid construction also minimizes lateral movement so the jack stays steady while you load, level, or rest in your RV.

• 4-inch height and 11.22-inch square base for broad support
• Holds up to 10,000 lbs per block (40,000 lbs total for a 4-pack equivalent)
• Prevents wobbling and distributes weight evenly across surfaces
• Compatible with tongue jacks, stabilizers, scissor jacks, and post feet

What materials and durability features does it offer?

The pad is molded from super-strong engineered plastic formulated to resist UV degradation, oils, heat, water, and dirt. Those qualities preserve strength and appearance through seasons of outdoor exposure so the pad remains functional and easy to clean.

• UV-resistant polymer that avoids cracking and brittleness
• Oil and water resistant to prevent chemical and environmental damage
• Heat- and dirt-resistant for reliable outdoor performance
• Tested load capacity to ensure dependable support under heavy loads

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

CircleRoad added a practical rope loop at the base so you can lift, drag, or hang the pad without touching dirty surfaces. The compact, stackable profile makes it convenient to store in a garage, RV compartment, or trunk.

• Built-in rope for carrying or hanging when not in use
• Stackable shape saves space in storage bays or closets
• Lightweight yet heavy-duty for hassle-free positioning under the jack
• Easy to wipe clean after use on mud or gravel

Will this work with my trailer jack and what are the measurements?
