These are just a hair under 24" square. They have never been used and painted for inside use but had outdoor storage for awhile with a few scrapes and nicks. The plate is 1/4",the pipe coupling in the center is the high pressure forged steel type used in industial applications and is 2". Cut a riser pipe,screw it in there and put whatever top you need on it. I have four of these left. Selling for $125 each,shipping included. Please PM me if interested.
These are heavy units,great for mounting a vice,grinder,polisher,etc, and get them off your crowded work bench. $115 each now,shipping included.
