Documented dust port

2-1/2 in rear port / 1-1/2 in blade-guard port — measurement type unclear — verify before buying

Confidence in this documented figure: MEDIUM

Limitations & connection constraints

  • The saw has a 2-1/2-inch rear dust collection port.
  • The blade guard assembly has a separate 1-1/2-inch dust port.
  • The manual states the port sizes but not whether they are inside or outside diameter; verify against the listing before buying.

Before you buy

  • Matching the port diameter alone does not guarantee a complete, sealed, or compatible fit. Confirm taper, wall thickness, locking tabs, thread, shape, and material before buying.
  • Verify whether each measurement is inside diameter (ID) or outside diameter (OD) before purchasing. Nominal labels are search aids, not fit guarantees.
