These are very thick and sturdy. Stack well. If you’re using them on a fifth wheel with a round platform on the end of the leveler, you need to take that off and just use the pole itself. I wish it would accommodate the round platform at the end of the leveler instead of having to take that off

I use this to get the nose of my boat a little higher while sitting on the RV pad. The solid construction handles the weight of the boat well. The boat trailer jack has a wheel on the bottom and the Jack Block has the perfect notch for a jack wheel. It's a simple device and one might argue pricey. A counter-argument would be that I built my own jack block of out wood previously (4x4 and 2x8s) and it broke from the weight of the boat after a couple years use. I think this jack block will hold up better and is worth the money.

We were looking for blocks to store our cab over camper on at home instead of cement pier block's. These fit the bill our truck needs tall blocks to drive out from underneath it to load and unload, we talked about figuring a place store wood blocks in the camper should we need to remove camper from truck. Now we have solved both problems. These blocks aren’t light either but less then it would be with heavy duty wood blocks and these are all weather and also has an area raised around the middle that cradle the legs of our landing pads. These will definitely outlast us buy it once and done. It would also work well for a trailer tongue block. Made in USA *****

I have a total of five of these. One for over a year and four I purchased in June 2024. I have an inclined driveway and I use two under each of the front stabilizers and one under the front trailer jack. They have held up well to heat, sun and cold. When stacked they have a nice secure interlock. They are a bit heavy, but are solid and well made. I would definitely purchase these again.

Excellent quality. Just check for bugs after each use… the crawlers like to hide in the blocks crevices…

This OX BLOX Trailer Jack Block was a nice upgrade from the old piece of wood we used prior to purchasing the OX BLOX, though I do feel slightly less manly without all the splinters. Sure, they're a bit on the expensive side, but I don't see ever having to replace these, and as they say, you get what you pay for.Our travel trailer jack takes 2 OX BLOXs stacked, as the location it typically is parked at has a slight grade to it and is not flat. It's very strong and well built - we love the fact that it's made from 100% recycled materials and in the USA! I appreciate the finger holes as it makes lifting and storing/un-storing easier. It is a bit on the hefty side, but the added weight certainly adds confidence that it will last much longer than other competitors or our old piece of scrap wood we replaced.
