I have two DW733 planers. I bought one new and it came with a plastic hood. Nice because you could just snap it on and off. But it would sometimes fall off from the vibration. I ordered this hood for my 2nd planer which I bought used and didn't come with a hood. Much nicer! Screws on SOLID and won't vibrate off. Ok, so you have to unscrew it to access the knives...but how often is that done anyways?
