This is the standard shaft that is shipped with the Mach2GTO. It is the same diameter - 1.125" - and uses the same counterweights - 6 lb. (6SLCWT), 9 lb. (9SLCWT) and 14 lb. (14SLCWT) - as the shafts for the 400 and 600E mounts. The end that attaches to the mount's declination axis was re-designed and incorporates a lead-in to start you out right and a shoulder to stop the shaft firmly against the counterweight shaft adapter without any binding.

The usable length is 13.675" and it will hold over 60 lb. of counterweights. The shaft itself weighs in at 4.1 lb. (1.8 kg)

This shaft requires the Machined Safety Stop Knob listed below.

This shaft is recommended for: all 400, 600, 800 and Mach2GTO mounts produced. This counterweight shaft can be used on mounts equipped with shaft encoders.
