Looking for products to support conduit for underground on resi projects. Usually we just use scrap rebar and whatever else we can find to hold conduit up right and floor boxes from shifting.

Wanting to use better methods with materials designed for such. Supply house doesn’t carry anything and I’m not sure what to search for.

Need something to hold and space conduit upright into walls, floor boxes staked into ground so they don’t shift, and some kind of stake to hold down the lateral runs of conduit between boxes.
 
Unistrut and straps can be used to space and support conduit coming up into walls if you're willing to spend the money. It can also be used for everything else you mentioned. Rebar stakes and tie wire is a cheap and effective to hold conduit down. Are you concerned about conduit floating up during a concrete pour?

No so much it floating up but getting pushed and causing floor boxes to tweak out of square. And everything else so big it’s not practical to hold the actual floor box. But I read somewhere guys use like 18x18 paver or something and mount the box to it.

Def not spending the money on strut.
 
Also the issue with using rebar to say hold something upright for the kitchen island, you can’t cut it down easily later on.

Plumbers seem to have a plastic stake that has 3 beveled edges. Just don’t know what they are called to search and buy them.

Rack a tiers makes a product I believe now although I’ve never used it, but upright into walls , I’ve used all thread and tie wire and it’s worked well

Maybe you're seeing some type of ground stake? Sioux Chief makes some but they don't quite match your description.


If you see plumbers in your area using them ask them. Maybe they get them at a local supply house.

If you use fiberglass rebar you should be able to cut it with a multi tool after the pour. In my area fiberglass is cheaper than steel.
