Important Installation Note: The Grommets are manufactured to be slightly less that the hole size. For example, if we have a grommet advertised at 1.0 inches (example size ONLY), when measured on a caliper, it will measure at approx. 0.96 inches - or approx .04 inches LESS than the hole size of 1.0inches. This difference is by design to allow for the grommet to be inserted into the CUT hole size. These grommets after inserted into a cut hole are intended to move freely. If you need a TIGHT fit, a small amount of glue or silicon may be needed.
