Manopole di blocco supporto specchio Sure-Lock per Celestron EdgeHD OTA (19792)

The brass machining is noticeably precise—each knob threads on smoothly without any wobble. They sit low enough that my focuser finally clears the rear cell without me having to fight for space. A bit pricey for what they are, but they solved the clearance issue exactly as described.

Finally got my TCF-Leo mounted with proper clearance thanks to these low-profile knobs, and the machining on the solid brass is noticeably smoother than the stock ones. They thread on with zero wobble, which is exactly what you want when you're fine-tuning focus in the dark.

These knobs slid right into place on my C14, giving me just enough room to fit the focuser without any modifications. The low-profile brass design feels much more solid than the stock plastic ones.
