Wall angle for use in suspended ceiling grid structure and including multi-purpose measurement indicia

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. A first series of markings are placed at first selected one foot length intervals along the body and for marking first iterative locations for engagement of the main runners and hanger wires. A second series of markings are placed at second selected length intervals, typically at sixteen or twenty-four inch intervals, along the body and for marking locations for engagement of the wall angle to vertically extending wall studs of the walled enclosure. A third series of markings are placed at third selected length intervals along the body and for establishing a selected overall height and length of the grid structure, the third series of markings each further defining a pair of markings provided along both the first and second sides of the body, the individual pairs of marks being established in opposing and substantially triangular shape and capable of being incised to create supporting channels for a resiliently engaged marking indicia.
