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.

Heavy Duty. Robust & Sturdy.
Heavy duty, nice and tall. Replaces the wood blocks I was using. Made of recycled plastic so it won't rot or rust, but it is a bit pricey. However, it is indeed very robust. Contemplating getting another one since they are stackable which would save a lot of cranking the jack handle around (mine seems to be geared very lowly).

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!

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.

Excellent well made
Bought this OX Blox about a year ago. I was using a piece of an old stump that finally rotted. I don't know why I waited so long to get one of these. Maybe because the stump was free... lol.... but yeah, this thing is rock solid for my dual axel cargo trailer.

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.

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

Solid quality.
These are exactly what I needed to replace the yellow plastic square supports. I’m using them on the manual stabilizers and the front power jack and they adapt perfectly. They look better too. These should be the last I ever need to buy.

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