Rubber Gasket Grommets
AirGuard's AirBlock rubber gasket grommets all feature the same UL 94 VO rated flame retardant ABS polycarbonate plastic found in all of the other AirGuard grommets, plus the added feature of EPDM rubber as a "foam rubber" sealant to hold the cables in place and prevent air from leaking around the cables. The AirBlock rubber gasket grommets have pre-cut knockouts or holes designed to accomodate from one to five 1/2" to 3/4" cable penetrations through the grommets.
The Square, Rectangular and 6" Round all incorporate covers to protect the rubber gasket material until the cables are fed through the floor opening.
If you have a set number of power cables or small bundles of data cables being run through your raised floor, the AirBlock grommets might be the perfect solution for enclosing smaller raised floor cable cutouts. Each AirBlock comes with its own integrated screw toggles to quickly lock the grommet in place once closed around the cable or cable bundles.
