Create a steadier parking setup for your recreational vehicle with two black trailer jack blocks, each 6 inches high and supporting up to 6000 lbs or 2722 kg. Made from tough polypropylene, the cylindrical blocks enlarge the support area beneath compatible jack legs and help provide stable positioning on uneven or soft ground. The universal design fits round and square metal jack legs, trailer support wheels, and insertable legs, making them suitable for fifth-wheel trailers, camper trailers, and Class A and Class C RVs. Use them on snow, grass, sand, gravel, dips, and rough surfaces, while the non-slip grip helps keep jack legs positioned on most surfaces. The taller profile adapts to uneven terrain better than thinner pads, supporting a smoother camping setup for RV parking and travel.
