A 3-piece design makes this an all-around performer. The rubber top and base are grippy and stable, while the plastic core supports over 40,000 lbs. Supports trailer jacks and stabilizers or can be used as leveling blocks for even the largest RVs.
WOW! I am impressed! I called to place my order and real person answered, spoke perfect English, albeit a slight southern accent, and my order was sent within a day, shipped quickly and I had it a few days later. I saved over a hundred dollars over local and installed it my self. I cant imagine how that they could do any better. THANKS!
