The bottom line: these two recycled-plastic blocks are built to handle heavy loads and wide jack feet, making them a practical choice for owners of travel trailers, 5th wheels and motorhomes who value durability and versatility. The reviewer found the blocks especially useful for larger tongue jacks, round and square stabilizers, and situations where a larger landing area improves stability.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAll-in-one fit:\u003c\/strong\u003e Works with square jack foot, round jack foot up to 9 in, 2 in tongue jack post, 6x2 in tongue jack wheel and scissor stabilizers so one product covers many needs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh load capacity:\u003c\/strong\u003e Each block is rated to support up to 15,000 lbs, providing confidence under heavy trailers and 5th wheels.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable construction:\u003c\/strong\u003e Made from recycled plastic with anti-UV additives for thicker, denser structure that resists aging and outdoor exposure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStackable height:\u003c\/strong\u003e Single block is 6 in tall and can be double-stacked to 10.4 in for additional height when required.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLarge round landing:\u003c\/strong\u003e The round top design increases contact surface and stability for jack feet and wheels.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe OULEME jack blocks are a good match for RV owners, camper and travel trailer users, and anyone with a 5th wheel who needs a sturdy, all-purpose leveling block that accepts multiple foot shapes and tongue jack wheels.
