On an installation where cut border tiles are present, the wall bracket will be installed so that the long leg is screwed to the ceiling with the short leg facing the floor. If your room is longer than 8 feet and you need more that one wall bracket, the second wall bracket will abut to the first wall bracket. At inside corners, the wall brackets can be mitered, inserted inside each other or abutted to each other. We suggest abutting the wall brackets if you are using a flat panel.
