They work great
These are simple, but they're well made, heavy duty, and they do the job. I'd recommend them.

Last BLOX you'll ever NEED!!
These things are incredible!! Originally purchased more than a year and a half ago to hold a HUGE destination trailer. These things show ZERO wear and seem as though they're virtually indestructible to the elements. Despite needing 5 for my setup it provides unparalleled stability and makes the unit feel as solid as the ground it sits upon. Worth EVERY penny!! Couldn't be more proud that this level of superiority is MADE IN THE USA!!

Solid and sturdy
I love this. I use it with my horse trailer which has a weird foot and we hook up different truck to it. It’s always the right height, short enough it fits under the foot even with the smaller trucks but tall enough I can jack up the trailer for my bigger trucks. It’s heavy duty, solid, versatile and survives all the weather.

No More Splinters
Lightweight but strong and durable. Had been using a big wood block - not only heavy but splinters at times. This is a great replacement - well worth the price.

OX BLOX are Wonderful
These are GREAT! They hold the stabilizer jack firmly in place - no more guessing with a stack of 2x4s. I would highly recommend them.

Solid
I really like this block. It's very very sturdy with a good sized base. It's solid and has some weight to it. No complaints at all. UPDATE: I've had this for almost two years now and it still serves it's purpose, but it's definitely becoming slightly concave on the top. Doesn't seem possible, especially since I'm no where close the weight limit, but it bows in a little from the weight. If buying again, I might try a different brand.

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