This is a replacement for the original dust shroud for the Dewalt 735 Planer. It has a 90 degree elbow for those whose dust collection systems isn't directly behind the planer. I included both 2-½" (seen in the picture) and 4 inch varieties, opting for separate models since you are likely only going to need one or the other, not both at once.

If you are replacing the existing dust shroud, reuse the screw that is securing that one to the planer. If yours is lost, you may have to find yourself a self-tapping screw. I don't actually know the correct size for the screw. You are on your own for that part.
