Takes a beating.
Very sturdy, could have another stop or nub on the side to keep the trailer from sliding a but its good for the job its doing.

Sturdy and dependable!
Great product! Have used this for a few years now on several different trailers. Very sturdy and good weight. I do recommend covering finger holes on sides with duct tape or will get critters in there!

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.

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!!

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

Good quality—low value
Expensive for what it is, but good quality and serves the purpose

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.

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