The correct size hole is cut with a hole saw and the grommet inserted then finally the grommet fitting is pushed into the grommet. It is not recommended that Petroleum Jelly is used as a lubricant. A silicon lubricant though more expensive is better.

Please note if grommet is fitted and then taken out a number of times, it may stretch.
