Thule Conduit Box Midwall

An accessory to the Thule Conduit Box 3171 making it easy to separate and access short and long pipes.


  • By adding a movable midwall, Thule Conduit Box Midwall 3181, you can also separate long and short pipes.
  • Storing different lengths of pipe in separate spaces avoids the problem of short pipes “disappearing” into the front of the box.
  • Use the wire trace to pull out your pipes.
