iOptron Gear & Clutch Upgrade Kit for MiniTower Pro/II Altitude

Designed for their AZ Mount Pro and MiniTower II mount heads, the iOptron Gear & Clutch Upgrade Kit replaces the original stock altitude knob to provide better locking power to the altitude clutch. The upgraded knob has four levers that make it easy to tighten - especially when wearing gloves. The improved locking power is accomplished through the use of tapered surfaces on the ring gear and brass washer, which translate the applied axial pressure into both axial and radial pressure. This kit is specifically designed for the AZ Mount Pro and MiniTower II mount heads, and will not fit on the original MiniTower mount.
