Dust Chute for a Delta Miter Saw, model 36-255L. This may also fit other models. This part is designed to be an exact replacement for the original part, which degrades over time and breaks into small pieces. Please note that this saw has been discontinued and this part can no longer be ordered. Also note that dust collection is not good with this or any other miter saw I have used. Without the Dust Chute, it's practically non-existent.
