This extractor knob snaps into the back of any magnetic rotor. It must be snapped on prior to fitting the rotor to the shaft. It holds the rotor in place and allows it to be easily extracted. Works only with the type 1 Smart Drive stainless shaft. If you already have a type 2 shaft then by gluing a short length of M12 threaded rod into the end of this shaft you can convert it to a type 1.
Please note: An extractor knob is supplied with every magnetic rotor purchased.
