This is a genuine DeWALT replacement part to be used in sanders. The dust seal fits in the platen. It prevents dust from entering the device. This item is available as an individual replacement part, and may require a screwdriver to install.

Dust Seal - spare
Easy to install but platen came with seal already inlace, so I have a spare for the future.

Easy and Fast
I ordered a platen, sander pad and backing plate, and this dust seal for my DeWalt sander. The repair took less than five minutes and I bow have a works-like-new sander for 1/3 the cost of a new one, plus the old one is not cluttering up a landfill somewhere.
My family loves to repair and use items other people have thrown away. We have an entire woodshop of tools that only needed a simple switch, small part, cleaning, or a new cord. Table saw, miter saw, circular saw, drills, sanders, etc. All free except for the small cost of a cheap part.
Save money, save the earth, everyone wins.

My sander suddenly became hard to handle - like it had a mind of its own! I disassembled the bottom part of the sander and found out that the platen was damaged beyond repair.
There are 4 screws holding the platen and the backing plate. Begin by unscrewing the backing. There are two clamps mounted on the backing which can be reused if you are replacing your backing plate - save these for later installation. The platen comes off next. Be sure to clean all the debris or dust from the sander before installing you

Dust seal failed causing build up of dust that caused the breaking of the platen and plate.
1. Removed the worn down sanding pad and broken platen.
2. I noticed that one of the brass screw holes that I screw the platen to the sander base had become loose. This was the most time consuming part of my repair to fix (and probably would never happen to anyone else).
3. After reassembling most of the sander back together,
