Measurements for legacy Khalil Mamoon base grommets

These measurements apply specifically to the older Khalil Mamoon base grommets.

Thin rubber base grommet:
- approximately 115 mm internal circumference;
- approximately 135 mm external circumference.

Thick rubber base grommet:
- approximately 108 mm internal circumference;
- approximately 143 mm external circumference.

Rubber grommets can vary slightly as they cool and settle after manufacture, so treat these as approximate measurements. If a grommet is slightly loose, a small amount of insulation tape around the stem can improve the fit. Do not force a stem into the glass base.

If you need help choosing a grommet, send support a photograph and the measurements of your stem and base opening.
