- Most main
Tare 12' long and have cross
Tslots punched every 12 inches beginning 6 inches from each end.
- Refer to your layout sheet to determine the distance from the wall to the first cross
T. Now measure this distance along the top flange of the main
Tand locate the slot just beyond this point, as shown in Figure 1.
- From this slot, measure back the same distance, subtract 1/8 inch and saw the main
Tat that point. The 1/8inch subtraction is for the thickness of the wall angle.
- If the wall angles are not square, position the cross
- When main
Tare installed in rooms less than 12 feet across, cut the main
Tto the exact measurement of the room, allowing 1/8 inch for the thickness of the wall angle, as shown in Figure 2.
- Remember that if the distance is less than a full main
Tlength, you do not want the mating flange to remain.
- For rooms wider than 12 feet, the main
Tcan be spliced, as shown in Figure 3. Be sure to align the splice so that the suspension wires are correctly positioned. Splice carefully, or all the main
Twill be thrown off.
- Install the main
Tso that they are all level with the wall angle already mounted. Use a long level or a laser level to perform this task.
- Install the cross
Tby inserting the ends of the cross
Tinto the slots in the main
T, as shown in Figure 4. Use the manufacturer's instructions for fitting the cross
- Determine the location of the cross
Tby the pattern you selected-either 2' × 2' or 2' × 4'.
- Be sure the lock tab on the cross
Tis on the outside of the slot. This attachment is slightly different in some types of
- You can remove most cross
Tby depressing the lock tab with a screwdriver.

- Your final main and cross
Tarrangement will look similar to Figure 5. The top part of the drawing shows an arrangement of a 2' × 4' layout, while the lower half shows main and cross
Tarranged for a 2' × 2' layout.
- Drop the ceiling panels into position by tilting them slightly (Figure 6), lifting them above the framework and letting them fall into place.
- If it is necessary to cut a ceiling tile to width and/or length it is best if you score the surface with a razor blade or utility knife before cutting. This will ensure that you do not have pieces of the ceiling tiles breakaway when cutting.
Make sure that your hands are clean, after setting each tile!
