Part: Telrad

These stainless steel knobs replace the small plastic aiming knobs on the Telrad reflex finder. Price is for a complete set of knobs.

Installation instructions:

1. Tighten the three factory knobs by hand until they become slightly harder to turn. Do not force them.
2. Remove one factory knob and replace it with a Bob’s Knob. Repeat for the other two factory knobs, one at a time.
3. Loosen the new knobs two or three turns.
4. Mount the finder on your telescope and align.
