UV-protected plastic resists weathering while drain holes and an ergonomic grip keep each block practical for frequent use. The kit's 10\" platform and 2.5\" center hole accept most jack feet so you can use one solution for tongue jacks, scissor jacks, wheel jacks and even 5th-wheel applications.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this jack block support heavy trailers without sinking?\u003c\/h3\u003e\n\u003cp\u003eThe TOWKING block uses an anti-tilt cone base plus eight reinforcement ribs to distribute weight and resist lateral movement on soft or uneven ground. The wider 10\" platform increases contact area so pressure is spread across a larger footprint, reducing the chance of sinking into mud or sand.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e12,000 lb rated heavy-duty UV-stabilized polypropylene construction\u003c\/li\u003e\n  \u003cli\u003eAnti-tilt cone base and 8 load-bearing ribs for stability\u003c\/li\u003e\n  \u003cli\u003e10\" platform increases ground contact and reduces ground pressure\u003c\/li\u003e\n  \u003cli\u003eDrain holes prevent water pooling and add durability\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill these blocks fit my trailer jack foot?\u003c\/h3\u003e\n\u003cp\u003eYes — the TOWKING blocks are built to be universally compatible.
