Peter, No it’s just a tray with welded up corners to remain coolant tight.
Some holes in the bottom that line up with the tee slots for fastening and draining.
I have some that take a vise sideways on and front ways on.
I also have a couple that are big enough for double vises.
I can get pics if needed but that are not works of art at all, just trays belted up by the local sheet metal shop.
