ars-imago LAB-BOX Additional Crank, Black

This crank can be used instead of the standard knob for a more comfortable agitation, especially when it is continuous.The Crank accessory eases the external control of the internal reel. It consists of two pieces: a fixed one and a movable one. Once you have inserted the disc aligning the plastic line with the symbol on the tank, turn the disc by 90 degrees to keep it locked. To uninsert the Crank, realign the line with the symbol and pull outwards. Before you use the Crank, check that the internal cylinder is clean in order not to cause damage to the gasket.
