Product Details
✓Built to Last: Crafted from high-performance polymer, the RV jack blocks hold up against sun exposure, mud, and oil. Integrated drainage holes ensure no water accumulation even on rainy days, engineered specifically for diverse outdoor conditions
✓Strong and Stable: A wide base combined with a solid one-piece structure allows the ROBLOCK trailer jack block to eliminate sway and sinking of the RV effectively. Even on uneven ground, it creates a steady living space for you. G.V.W 40000 lbs
✓6" Extra Height: The increased height of the 5th wheel accessories means your jack doesn't need to extend as far, greatly improving the efficiency and stability of leveling. This design makes it much quicker to lift your RV and lessens wear on the jack
✓Flexible Stacking Design: A unique interlocking design allows the RV trailer accessories to be firmly stacked, and you can easily adjust them to the right height. After use, the stacked blocks can be put into the included bag, ready for the next adventure
✓Lightweight and Portable: Each block weighs just 2.81 lbs. With the handle and rope, you can easily carry the RV blocks wherever you need them. They are excellent for taking on camping trips so that you can leave heavy pavers or wooden blocks behind
✓Versatile Compatibility: With a dimension of 11.6 x 11.6 x 5.91 inches per block, it supports nearly any tongue jacks, wheel jacks, scissor stabilizers, and more. Whether snow, grass, sand, or gravel, it ensures a level and solid foundation for your campsite
