ABSTRACT:
A device for aiding installation of suspended ceilings includes a first cross member having an upper face to be disposed adjacent a bottom face of a main-tee and a second cross member extending from the first cross member at 90° and having a an upper face to be disposed adjacent a bottom face of a cross-tee. The first cross member has an upwardly extending retention lip having a slot formed therein to frictional receive a portion of the main-tee in a manner to retain the device thereagainst. The second cross member has an upwardly extending guide lip which in conjunction with the adjacent upper face provides an abutment against which the cross-tee may be disposed such that the cross-tee is at 90° to the main-tee thereby enabling easy permanent riveting of the tee to the wall angle. A method of installing a ceiling grid is also provided.
