Durock Magnetic Rock

Usually you could just call a magnetic rock a magnet I think, but hey here we are. Come to think of it, Durock Rock is a weird name too. Idk, I don't have a lot to say about this besides it's a JWK magnetic switch. There seems to be a similar but technically distinct version that Everglide is selling, but honestly I didn't look that closely. It's a POM stem in a presumably PC housing. 

Initial Force: 35g

Bottom Out Force: 48g

Bottom Out: Not noted but from a force curve looks like 3.4mm
