The unit also comes supplied with all fitting hardware and more importantly a safety cover. This means the unit can be installed well in advance of computer racks without compromising safety. The GTAG7 is easy to cable and the neoprene gasket stretches to accommodate large cable bundles. All of this adds up to making the GTAG7 the best value large brush grommet on the market.
