Modular Wood Cube panels are installed into a 15/16 inch heavy-duty T-Bar grid. The lay-in cube panel rests on the backside of the grid flange, leaving the bottom surface of the T-Bar exposed. The exposed T-Bar flange can be covered with matching wood trim. The Recessed Tegular cube panel drops into the grid helping to mask the T-Bar flange. Modular Panels are made in 2′ x 2′, 2′ x 4′ and 4′ x 4′ sizes.
