Can these be sand filled and has anyone done it?

Only if you were to plug the bottom but there is really no need they are very sturdy and unless you use them for tackling dummies they are not going to fall over. I've had them for more than 2 years and I LOVE THEM.

I'm not sure if you need to fill them with sand, they are fairly heavy and stable. The lowest height adjustment is about head height if you're sitting down and there are a few more adjustments with the little pegs to make it higher. Top plate is free to spin around. I have JBL 5" monitors on mine on a carpet floor and it easily handles those. There are small spikes on the bottom to dig into the carpet for stability. I wouldn't go much bigger than 5" monitors as the top plate is only slightly larger than my speakers. 8" speakers would probably overhang the edges but I'm sure they could handle the weight.

I would say yes if you sanded them you could paint them. Stain... not sure. Good luck!

Yes, they are sand filled and at best travel 10'. They are great for warm-ups or strengthening swings, we use them for our 9/10 year old little league team. They give great response on whether the ball is struck well or not.

Yes. Comes with instructions on how to fill with sand and bricks if desired.

Yes you can put sand in it. You can put water, marbles, dried beans, etc. in it.

Yes. We haven't filled it with sand yet but over the weekend we moved the box and it was dry inside.

I have no idea...,but I don't think so w/material covering and sand type filling.

We have not tried that. They are very hard unless soaked. They are pretty small, however.

As a matter of fact, I used them last night. I saved 2 16 oz. glass pickle jars with metal lids and filled them with sand. After they burn out put the lid back on and you can leave them out side and they won't fill with rain. This worked great. Last year I just filled a plant pot with soil and would just stick them in it but the wind would keep blowing them over.

There r some what water proof but I had to use 500 pound of sand to fill them

I've never tried but probably wouldn't. Most of these things are fairly banged up and there's no rubber seals or anything to keep them from leaking. Don't let the dents scare you though, 15 minutes with a rubber mallet and S.O.S. pad and they're back in great shape.

They are not hollow. I guess you could drill a hole-they are pretty small though

Probably not. I have not tried them in sand, but I do not believe they will hold in sand.

I have not tried, but feel it would be an excellent choice. Since they are not clad, you may wish to place them inside a cast iron skillet for the same heat distribution effect that cladding would provide.

I move them a lot, and have not had any problems either. Sandbags can work to stabilize them in windy conditions if needed.

I use them indoors right now, but I would think a strong wind would knock them over. Someone else suggested filling them with sand to keep them steady.

I'm not sure... We used the exact amount of sand recommended and have had absolutely no problems. A little sand initially when we submerged the steps but I think that was just from a little spillage onto the steps as we filled them. No movement, no floating. We love the steps. They are exactly what we were looking for.
