Keep your RV stable, eliminating most movement and sway with the strongest jack blocks on the market. Unique design provides the most stability and strength.
Perfect fit for 9" large round jack feet found on many 5th wheels and other RVs. The corner ridges keep the foot secure and stable. The shorter height (4.25") make them convenient for stabilizer jacks, compared to the bucket block.
10,000 lbs. capacity. The larger surface area created by the web design on the bottom of the block is a more stable surface area than alternative blocks.
Size: Recessed pad area is a 9.25" circle with a 5.25" gap between ridges. The block is 10.5x10.5x4 and weighs 6.8 lbs. The block is made in the USA of UV-resistant recycled plastic.
Patent pending design by American engineers. These heavy duty blocks are made the old fashioned way, and are built to last.
