Meade telescope ETX90 RA altitude lock knob & threaded shaft

Excellent Condition FROM MEADE! This is an aluminum knob with a press fit steel threaded shaft coming out of it. This was originally made for the ETX90 RA model to lock the altitude of the telescope. The knob is 1/2" in diameter and 5/8" long. The steel shaft is 2" long out of the knob and 1/8" in diameter. The threads are about 32 per inch, that is my estimate. I would guess it to be a 6-32 thread but that is just my best guess. If you can use a nice knob with a steel shaft coming out of it, here it is. if you need another thread size you can always cut off the thread and rethread the 1/8" shaft to your needs. A nice piece of hareware. The price is always right at the telescope warehouse!
