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

Abstract

A wall angle and main runner 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 measurement indicia scheme is placed in an incrementing manner along the first side and in a correspondingly decrementing manner along the second side, such that the elongated body is reversible to illustrate a selected incrementing/decrementing indicia scheme along either extending side. The main runner exhibits an elongated body with a first end and a second end and an indicia scheme is placed along the main body at ½″ intervals between the first and second ends.
