The 45 mm ground anchor metal is suitable for all Brabantia Topspinner and Lift-o-Matic dryers. Place the ground anchor in a soft surface, such as grass or earth, and your Topspinner or Lift-o-Matic drying mill is sturdy. The anchor consists of galvanized steel; it doesn't rust. Do you get your drying mill out of anchor? Then close it with the cap. This keeps the ground anchor free of dirt.
