19" long x 2' wide x 1/4" thick. 5/8" hole at top and other holes are 3/8". The 5/8" hole is easy to shim down to 1/2" with an insert made from 1/2" pipe which I have. 316 Stainless steel. I made these for my boat when I was unable to get the 3/8" thickness I wanted initially so made do with this thinner stock for awhile. $50/ea. Two are polished and 2 are not. I also have stock to make five more 15" long.
