Non-Vision Transfer Grilles Single & Double Cores

Type DTG/WTG Core Only

This grille has been specifically designed for mounting in a heavy duty raised access floor, suitable for computer rooms or other areas where floor supply is advantageous.

Extensive testing by independent laboratories have certified that the grille is suitable for meeting the stringent point loading and safety factor requirements for these areas. The grille is also suitable as a general replacement for 600sq floor tiles where areas of heavy foot traffic and equipment would be experienced.

These are particularly suitable for doors to staircases etc. where air transfer is desirable but fire requirements must be met.
