Tunze Magnet Holders can be used to mount all Turbelle pumps,Comline components and for all DOC Skimmer (exept 9002).
All other TUNZE® units, such as the sensors of Osmolator 3155, Osmomat, et cetera, can also be mounted, provided the standard sliding unit fits into the magnetic holding device, which consists of two magnetic parts.

The inside part is located in the water and the outside unit is on the outside of the aquarium. Both parts are of identical shape. The inside part with the sliding unit can be used to easily position the pump or Comline component at the requested location on the inside of the glass pane. Subsequently, the outside unit has to be placed at the same position on the outside of the glass pane.
On account of its encapsulated construction, the magnetic holder is noncorroding and has no detrimental effects on the aquarium biotope.

can be used for glass panes up to 19 mm (.74 in.).
