Patent ID: 7207144

Claim:
A device for aiding installation of a suspended ceiling grid which uses main-tee and cross-tee construction, which includes: a first cross member having an upper face to be disposed adjacent a bottom face of the main-tee and a second cross member extending from said first cross member at a predetermined angle and having a an upper face to be disposed adjacent a bottom face of the cross-tee, said first cross member having an upwardly extending retention lip having a slot formed therein, wherein said slot is of width to frictional receive a portion of said main-tee in a manner to temporarily retain said device thereagainst with said upper face held in place against the bottom face of the main-tee, said second cross member having an upwardly extending guide lip which when said retention lip is connected to the main-tee, said guide lip in conjunction with said adjacent upper face provides an abutment against which the cross-tee can be disposed with the bottom face of the cross-tee facing said upper face of said second cross member such that the cross-tee is at said predetermined angle to the main-tee thereby enabling easy permanent riveting of a main wall angle to said cross-tee together, and wherein once the cross-tee is so connected to the main-tee to form a permanent cross structure portion of said grid, said device is configured to be removed from said permanent cross structure portion.
