No hole in the bottom to mount to a dial, if wanted, drill it, unit is solid and sturdy, perfectly accurate!
Description
This is an awesome two part resin crank knob that was cast from an actual vintage part. It is made in a durable and strong light grey resin, that is a very close match to the knobs used on the GB1 pack. Some slight cleanup of the pour surface may be required. Assembly will be required using either glue or a mechanical fastener.
