These heavy-duty rubber curb ramps are seriously tough and practical for so many situations! Each ramp stands 5.2 inches high, 12.75 inches long, and 19 inches wide - substantial enough to handle serious weight while providing a gradual incline. Made from industrial-grade recycled rubber, they can support up to 20,000 pounds, which means they'll handle pretty much any vehicle, cart, or equipment you need to move over curbs. The pre-installed mounting holes allow for permanent installation if you have a frequent need, or you can just place them temporarily as needed. The rubber material provides excellent traction even when wet, preventing slips and making transitions smooth and safe. They're perfect for loading docks, driveways, warehouses, or any situation where you need to move equipment between different level surfaces. The two-pack is practical because you can create a wider path for larger vehicles or have one for different locations. Just note that new rubber has a natural odor that will dissipate if you leave them outside for a bit initially. The durability is impressive - these aren't flimsy plastic ramps that crack under pressure; they're substantial, weighty pieces that feel like they'll last for years of regular use. Whether you're dealing with delivery trucks, lawn equipment, wheelchairs, or just want to make your driveway more accessible, these curb ramps provide a simple but effective solution. They're one of those products that once you have them, you find yourself using them for all sorts of situations you never anticipated.
