Each block measures 10 1\/2\" x 10 1\/2\" x 1 1\/2\" and features a quad-grid engineering pattern for increased load capacity and resistance to crushing. The set includes ten gray blocks with an integrated T-handle for convenient carrying and compact storage; stacks are intended for use up to 4 1\/2\" high.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these blocks make leveling an RV faster and safer?\u003c\/h3\u003e\n\n\u003cp\u003eStackable, interlocking faces let you build the exact height and footprint needed without slipping or shifting under weight. The larger XL footprint distributes load over a wider area, reducing sinkage on softer surfaces.
