Listing is for a pair of knob grips.

Replacement rubbery grip for common focuser knobs used on many telescopes including Celestron, Orion, Sky-Watcher, etc.

The original rubber is thin and is prone to wearing out and cracking. These are slightly thicker/stronger. 3D printed with soft flexible TPU filament, with the OEM size and grip pattern. Get your telescope working just as it was designed to! Lifetime warranty on these if anything happens I'll replace them for free.

The inside chase of the knob without rubber measures about 40mm across (39.9mm to be exact), and the rubber is 12mm wide. If you need custom grips please message me, I would be happy to make you whatever you need (even for lenses, binoculars, spotting scopes, etc)!

Fast shipping, returns accepted, Made in the USA, your purchase helps me support my family! Thank you!
