The 1-1/2″ T-Grid System is designed for Class 10,000 and 100,000 Cleanrooms or ISO Classes 7 to 9.

Standard opening sizes are 22-1/2″ x 46-1/2″ for accepting Fan Filter Units, Cleanguard Ceiling Panels or cleanroom light fixtures.

The white closed foam cell gasket is factory applied for best results, with compression sealing the gaps between system members (i.e., main tees to cross tees and wall angle) and other components.

The G30 hot dipped galvanized steel body and cap, painted flat white provide unequaled corrosion protection and also meet or exceed all national code requirements, including seismic.

Installation and assembly requires no special tools.
