Camco’s Leveling Block Caps fit onto the top of Camco Leveling Blocks (sold separately) to form a smooth surface. The caps help create a more stable, secure surface for jacks and stabilizers to operate on by distributing the weight of the vehicle more evenly. If you only need one block worth of height, you can use the caps to connect two adjacent blocks together. You can also stack one cap on top of a single leveling block to create a stabilizing jack pad. These blocks increase the versatility of the leveling blocks and create an ideal surface for scissor jacks, trailer tongues, stabilizers, wheels and more.
