I have a downdraft table attached to the back of my bench, hinged so it folds down, that i used to use for that purpose before getting the Festool Sanders. Effectivley it is 30" x 42" x 4" deep with 3/4" holes 2" on center. It hasn't been used for anything except support and workspace since I got Festool. All my other brands of sanders sit idle. It did work well with my DC to get the dust from my Bosch & PC sanders, but at this point, I guess it has outlived it's purpose.
