2ʺ x 2ʺ Installation
1. If you are using 2 x 2 panels, you need to lay out your grid differently.
2. Determine the size of your border panels from side to side.
3. Place the first main beam the border panel distance plus 2 feet from the wall.
4. Cut 4 cross tees to the wall and insert 2 cross tees between the 4 cross tees to establish the border panel
openings.
5. Your main beams will then fall on 4 centers from that point.
Cutting “recessed grid” ceiling border panels
1. Trim reveal edge border panels to the same dimensions as for flat panels. The reveal edge detail must now
be cut into the panel.
2. Set the panel into the grid. Draw a light pencil line on the panel using the wall molding as a guide.
3. Remove the panel. Use a sharp utility knife and straightedge to cut halfway through the panel from the face
side along the pencil line.
4. Lay the utility knife on its side next to the panel and, with the panel face up, cut in at blade height for a
reveal cut.
5. Remove the cut strip.
6. Fit the panel into the grid.
