Level your griddle with the Blackstone Leveling Shims Kit. This kit includes eight shims, each with 1/4" height gain per shim. Whether your griddle or grill has feet, casters, or both, these wedges work with it all. You can combine the Blackstone leveling shims to add more or less height to accommodate uneven ground on grass, dirt, or concrete. The grooves on the shims allow you to stack them pyramid-style to increase your footprint on soft ground so your griddle legs won't sink. The plastic material won't deteriorate over time so you can use them over and over again. When you're done, stack them up and store them to use them again next time.
