Frequently Asked Questions

I have SnapPads on my stabilizers, will they fit within the ridges of OX BLOX MAXX?

It depends on the size of the feet. For 9" round feet that are common on 5th wheels, they will not fit within the 9.25" diameter between the ridges of the OX BLOX MAXX. If your rig has smaller feet, it will likely fit. The best thing to do is measure your feet and compare it to the measurements image on this page.

Can it handle the weight of my RV?

Yes. Our listed weight capacity is 10,000 lbs, which is more than enough for any jack weight from an RV. In reality, the weight capacity is much more than 10,000 lbs. That’s just the weight a bare post started to leave a mark in the block. The jack feet we used in our testing began to bend before anything happened to the block. These things are solid and will not break under any normal circumstances.

Can OX BLOX hold up without cracking or breaking down in -30°F temperatures?

Yes. OX BLOX Trailer Jack Blocks are made primarily from recycled polyolefin thermoplastics, which have a service temperature range of -60°F to 275°F (-50°C to 135°C). This means they are designed to withstand temperatures well below -30°F without cracking or breaking down under normal use.

Can you sit two on top of each other?

Yes. OX BLOX Trailer Jack Blocks are designed to be stackable. Just make sure they’re placed on stable, level ground before stacking to ensure safe and secure use.

Can I turn an OX BLOX upside-down and use the flat side?

It’s not ideal, but on dirt or grass it should do fine upside-down.
