Abstract: A wall angle for use in installing a suspended ceiling grid structure within a walled enclosure, the grid structure including a plurality of main grid runners and hanger wires suspending the main runners from an overhead support of the room enclosure. The wall angle includes an elongated body defining, in cross section, an angled profile with a first side and a second interconnecting and extending side. At least one series of punch-out, die pressed, indented or etched markings are placed at pre-selected length intervals along the body and for marking iterative locations for such as engagement of the main runners and hanger wires and marking locations for engagement of the wall angle to vertically extending wall studs of the walled enclosure.
