Instructions
1. Install an L bracket at the proper height around all exterior walls. Hang the main T braces at 4-foot intervals, then insert the cross T braces to complete the grid. Make certain all hanger wires are tight and the grid-work is level.
2. Install the ceiling tiles in all of the open areas around the Lally column. Turn the tiles at a slight angle and maneuver them above the grid-work. Allow them to gently drop into place. Once all of the tiles are in place the grid-work will be much more secure and firm, allowing you to take better measurements.
3. Measure the opening in the grid-work around the Lally column. Double check all measurements, then transfer those measurements onto a ceiling tile. Set a compass to match the diameter of the Lally column and place it in the center of the markings. Very carefully mark out a circle to match the position of the column.
4. Cut the circle out using the box knife. Attempt to keep the cut as clean and neat as possible. Be very careful when making the cut to keep your hands well back from the blade.
5. Mark a straight line across the tile using the square as your guide. The line should go directly through the center of the circle you have just cut out. Use the box knife to cut along this line and cut the tile into two pieces,
6. Insert the two pieces of tile into the grid-work, aligning the two half circles around the column. Angle the tile slightly to get it above the grid-work, then drop it into place. You may need to trim around the circle cut slightly to get a smooth fit. If so, make very small cuts, then check your fit.
