These OULEME blocks are molded from high-density polypropylene engineered to resist crushing and deformation, and their anti-slip features let you stack multiple layers with confidence. The design fits common jack foot sizes and tongue wheels so you can build the lift you need without improvising with wood or loose rock.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these blocks handle different jack types and wheel sizes?\u003c\/h3\u003e\n\n\u003cp\u003eOULEME blocks are shaped to accept square jack pads, round jack feet up to 9 inches, 2\" tongue jack posts, 6x2\" tongue wheels and scissor stabilizer feet.
