Abstract
Disclosed are embodiments of a round floor grommet and a rectangular floor grommet. These floor grommets can be constructed in any desired shape other than round or rectangular. Frame portions that hold foam pieces are joined together to form a primary slit in the floor grommet. Cross slits can also be formed in the foam material. The foam is a semi-closed cell foam that is constructed from PVC and nitrile butadiene rubber which has superior sealing effects since the foam can conform around objects passing through the slits in the floor grommet and seal any flow of air through the slits.
