Molded from UV-stabilized polypropylene, each block is shaped to accept most jack feet and includes drainage, ergonomic grips, and a quick-strap in a 600D storage bag. The design focuses on predictable stacking, no-wobble stability on uneven ground, and a compact kit that replaces bulky lumber or unreliable supports.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these blocks fit different trailer jack feet?\u003c\/h3\u003e\n\n\u003cp\u003eThe TOWKING blocks feature a 10\" platform with a 2.5\" central hole sized to accept most tongue, wheel, scissor, and fifth-wheel jack feet. The universal opening and broad contact surface distribute load evenly, reducing pressure points that can sink into soft ground or deform jacks. Their geometry keeps feet centered and prevents slipping during lifting or leveling.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e10\" platform accepts most jack foot sizes for broad load distribution.\u003c\/li\u003e\n  \u003cli\u003e2.5\" hole fits common jack studs and bolts without adapters.\u003c\/li\u003e\n  \u003cli\u003eCone-shaped base and 8 ribs resist lateral movement and soft terrain.\u003c\/li\u003e\n  \u003cli\u003eWorks with tongue jacks, scissor jacks, wheel jacks, and many 5th wheel setups.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eAre these blocks strong and weatherproof enough for long trips?\u003c\/h3\u003e\n\n\u003cp\u003eYes — the blocks are rated for 12,000 lbs and molded from UV-shielded polypropylene to resist sun degradation and seasonal temperature changes. The material choice offers long-term durability without rotting or splintering, unlike wood, and the kit’s drain holes prevent water pooling that could freeze or add weight. The included 600D bag and quick-strap keep the set secure during storage and transport.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e12,000 lb load rating per recommended stacked configuration.\u003c\/li\u003e\n  \u003cli\u003eUV-stabilized polypropylene resists cracking and sun damage.\u003c\/li\u003e\n  \u003cli\u003eDrain holes avoid water collection and freeze-related issues.\u003c\/li\u003e\n  \u003cli\u003e600D carry bag and strap for tidy, travel-ready storage.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow does the anti-tilt design improve stability on uneven ground?\u003c\/h3\u003e\n\n\u003cp\u003eThe cone base and eight radial ribs increase ground contact and bite, minimizing tilt and wobble on gravel, dirt, or soft grass. The blocks lock together securely when stacked, preventing lateral shifts under load and providing a predictable lift height every time. This reduces the need for constant readjustment during leveling or while hitching and unhitching.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eCone base sinks slightly into soft surfaces for a locked footprint.\u003c\/li\u003e\n  \u003cli\u003eEight ribs reinforce the block against lateral forces and shear.\u003c\/li\u003e\n  \u003cli\u003eInterlocking stack design prevents accidental slippage when loaded.\u003c\/li\u003e\n  \u003cli\u003eQuick, repeatable stacking gives consistent 6\" to 8.6\" heights.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat accessories come with the 4-piece kit and how do they help?\u003c\/h3\u003e\n\n\u003cp\u003eThe kit bundles everything to save you from piecing items together: stackable blocks, a quick-strap for secure stacking, and a heavy-duty 600D storage bag for neat transport.
