This station is geneally in very good to excellent condition. We found a couple cracks in the polypropylene on the circular flange that allows the unit to be hooked into a fume-exhaust system. This was likely caused by overtightening the previous exhaust-pipe setup on the hood. It looks as if it was repaired with silicone caulk. This part of the bench would be inside the exhaust pipe when properly hooked-up.
