Gromtec GTAG1 Air-Guard Integral AirGuard Grommet
The Gromtec GTAG1 Air-Guard features an overlapping brush system with 2 opposing bristle lengths which combine to provide an effective air seal around cables passing through the protective sleeve.
The unit is relatively narrow which facilitiates the use of shorter bristles which maintain their horizontal alignment and will not wilt over time. Note, long and heavy bristles (over 125mm ) are prone to wilting over time thereby creating an air gap opening in the grommet. The GTAG1 also features a removable edge section. This can be useful if the unit is installed at the edge of a floor panel. 2 units can also be installed face to face to form a larger cable way.
