These casters are hold the weight of the rack and firewood easily. My project is very heavy and made of 2 x 4's, cedar boards and concrete pavers so these 4 casters hold up beautifully. Double-bearing design for added durability.

I have a midi wood lathe on a cart - added these castors and they roll easily & quietly. I pull this around an apartment complex 5 days a week collecting trash. They go over uneven sidewalks, bumpy asphalt with ease.

Was not overly fond of the orange color wheels but not a deal breaker. They come with a set of nets, bolts and washers to install on metal or wood screws and separate washers for installing the wheels on a wood frame. The brakes work well.

They are easy to lock and unlock and very easy to move this heavy piece around on the patio. Unlocking them for movement can sometimes be a bit tricky.

The heads of screws are so small they had to give ya washers to keep from going through the holes. The swivel bearing is sloppy. The casters are only available in 4 or 8.

Great value and sturdy. Great buy cheaper than ikea or homedepot.

There is no way these can support the stated max load without flattening. Out of the 24 one was doa but 23 are ok. Quality is questionable.
