OX BLOX Ultra Trailer Jack Block - Universal RV Leveling Blocks - Durable & Stackable - For All Jack Types - 100% Recycled Plastic - Works For Class A Motorhomes

As advertised. Solid piece, so if you are looking for iso pad rubber style, this ain't it. However, used these in a farm field for my 5er, and they increased my power jacks footprint on the somewhat softer ground. Little rope handle is simple and handy. Very sturdy, somewhat heavy, solid piece for the jacks.I wouldn't recommend as a solo piece for a tongue jack of a pull trailer, but there are other options for that. Use these under the stabilizer jacks. I'd buy again, if they would somehow wear out or I lost one or something.I carry various options for chocks, jack pads, etc because one size does not fit all situations in camping. Be prepared.

Having both these and the larger version really makes it easy to level my RV with confidence. They are a bit heavy, but that's fine with me. We move almost every two weeks and have been using these for a little more than a year. Very durable. I added some rope handles to the existing holes to make it easier to place and remove. Highly recommend.

Very strong.

Very sturdy/stong....and pretty heavy as well, but I don't care about that!

Very strong and solid. The regular block did not fit my small trailer jacks. It actually Bent one . I noticed later that they have a bigger size but who would’ve dreamed that my 4 inch jack would not fit in the standard size one. Also the bottom is open so if you’re in sand you sink .

I was impressed by this product. It stores easily in my bays. It's clearly built well. We used it on a month long RV trip (we have a Class A motor-home). I really liked the handle that allows you to reach in and pull it out with ease. I ended up getting this product after my Snap Pad fell off, not once, not twice, but three times. I gave up on purchasing any replacement Snap Pads and went to this product. I wish I did it sooner. The footprint is much larger so, in wet grass or ground, it provides a wider "footprint" that keeps the coach balanced.

I purchased the Ox Blox Ultra and use them under my fifthwheel tires to get my unit closer to level before going to autolevel. I no longer carry six foot 2”x12”s planking to back up on to now that I have my Ultra pads. With the planks you always had to be lined up perfectly in order to get both tires onto the planks. With the Ultra pads I just place them one in front of each of my tires and then pull up on to them. Then I place my Ox Blox Maxx leveling blocks under my hydraulic levelers and then hit autolevel. In case you haven’t noticed yet I’m a big Ox Blox believer. “Look at the rest and then buy the best…..OX BLOX.”

Durable and works as intended. Very pleased with the product.
