conversion kit (adapter ring)

For retrofitting an existing CaliHeat fan mount to the 50°Nord VanHeat bayonet system.
The ring is simply attached to the existing fan holder.
Your fan is already compatible with the bayonet lock of the sleeping board.

INFO: You can also use the original CaliHeat fan mount on the sleeping board without a bayonet. However, the fan can be aligned and operated much better with the bayonet ring.
