Measure the area of your ceiling by taking a tape measure from one corner to the next and then from that corner to the next. These two lengths will give you the width by length dimensions. Take these numbers and divide them by two. This will tell you how many full 2-by-2 foot tiles the ceiling will have. On a sheet of paper, draw the dimensions of the ceiling and sketch in how many 2-by-2 foot tiles will fit in the ceiling area.
Measure 4 inches down from the ceiling rafters. Use a laser level at 4 inches down and mark a line along every wall. Screw the L-shape brackets around the line on every wall. If the bracket piece is too long or you need another piece of L-shape bracket, you can cut any ceiling bracket with a handheld metal shears.
Start constructing the main runners on the floor of the upside-down T-shape brackets that will form the 2-by-2 square tile areas in the ceiling. The brackets simply screw together. Screw in the suspended ceiling screw eyelets into the ceiling rafters every 4 feet. Screw the end of the upside-down T-shape brackets to the sidewall L-shape brackets. For every 4 feet of upside-down T-shape brackets you connect, connect the 16-gauge wire connectors from the eyelets in the ceiling rafters to the upside-down T-shape bracket. Connect main runners of these upside-down T-shape brackets both lengths of your room to create the square shape.
Start in one corner and work toward another. The room may not fit only perfect 2-by-2 foot tiles, and you'll have to cut brackets with a handheld metal shears and tiles with a utility knife to fit.
Stand on a stepping stool. Angle the ceiling tile and raise it through the squares created by the suspended ceiling brackets. Flatten the ceiling tile and lower it into the 2-by-2 foot square bracket.
