Screw slot ceilings offer a clean architectural appearance due to their narrow flange and
flush appearing tile. Installing a standard grid ceiling lensed or parabolic louvered
fluorescent fixture (shown below) into a screw slot ceiling may be viewed as undesirable
from an aesthetic standpoint. This is primarily because the fixture sits on top of the grid, and
creates a flat plane step up from the tile.

Lithonia offers parabolic and lensed troffers (shown below) with an optional screw slot trim
to eliminate the step up from the ceiling tile plane.
The RT5 was designed for universal application in both screw slot and standard grid ceilings
and has the ability to enhance the aesthetics of the space in either application. In the screw
slot ceiling the minimal flange and shallow arc of the fixture create an attractive reveal, and
the fixture is seen as flowing out of the ceiling plane.
