Made from weather-resistant polymer with integrated drainage, a wide base and a secure interlocking stack system, it performs across campsites, gravel pads and seasonal conditions. The 6\" profile makes it easier to lift your travel trailer or fifth wheel without overextending the jack, while the molded handle and rope keep transport simple and clean.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this block improve stability on soft or uneven ground?\u003c\/h3\u003e\n\u003cp\u003eThe ROBLOCK block spreads weight across a broad footprint to stop jacks from digging into sand, mud or grass.
