Note that your single speed focuser must have a tapped set screw on the underside between the two silver Tension and Focus Lock thumbscrews. Some single speed focusers do not have this extra screw hole between the two silver screws, and you will not be able to upgrade those models. Most, but not all, single speed focusers from GSO have this screw. However, please check this on you focuser before you order this kit.
This kit will work with compatible focusers from Meade Lightbridge, Hardin Optical, DSO, Antares, etc. It will not work with William Optics focusers.
