Short answer

The Bosch RA1172AT is a two-hood dust kit for the 1617, 1617EVS, 1618 and 1618EVS routers on fixed bases RA1161, RA1162, RA1164 and RA1165. Bosch names the VAC002 or VAC024 for 1-1/4 and 1-1/2 in hoses and the VAC020 for 2-1/2 in hoses. The catch: plunge bases are not on Bosch's list, and the hood's own port diameter is not stated. See router dust hoods.

Watch out for

  • Bosch's compatibility list stops at the routers and fixed bases it names. A plunge base or another Bosch router is not confirmed.
  • The hood's own port diameter is not stated, so Bosch's named adapters are the confirmed route, not a measured port.
  • Bosch splits the adapters by hose size: VAC002 and VAC024 for 1-1/4 and 1-1/2 in hoses, VAC020 for 2-1/2 in hoses.
