Posts are the same diameter to fit standard chrome wire shelving from the big box stores. I don't use them for food prep; I use them for shelving in a cine' film archive. The posts use standard 1/4-20 thread casters. The grooves are numbered which makes assembly much easier. The price is fantastic. I'm very happy with them.
