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, said wall angle comprising:an elongated body having, in cross section, a profile with a first side and a second side extending from an interconnecting edge with said first side; a first marking indicia laced at first selected length intervals along said body and for marking first iterative locations for engagement of the main runners and hanger wires; a second marking indicia placed at second selected length intervals along said body and for marking second iterative locations for engagement of said wall angle to the walled enclosure; and a third marking indicia placed at third selected length intervals along said body and for establishing at least one of an overall height and length of the grid structure, said third marking indicia further comprising a third series of markings designating increments beginning at an initial established length of seven foot, six inches along said elongated body, and repeating at six inch increments thereafter, additional third markings at further designated increments including seven foot-eleven inches, nine foot-eleven inches and eleven foot-eleven inches, said third series of markings each being inscribed as a pair of markings along both said first and second sides of said body, said individual pairs of marks being established in opposing and substantially triangular shape; said wall angle greatly reducing the time and effort necessary in establishing the necessary measurements for marking the main runner and hanger wire locations, the locations of wall studs associated with the walled enclosure and the correct height for the location of additional lengths of wall angle and a correct drop height of the main grid runners.
