Lithonia Lighting RT5 Installation guide

Hello! I've reviewed the product details for Lithonia's lensed troffer profile, S-Trim parabolic profile, and RT5 troffers. This document explains how these troffers are designed for both screw slot and standard grid ceilings, highlighting features like the optional screw slot trim and minimal flange design. I'm ready to answer any questions you have about these products.
Why are standard grid fixtures undesirable in screw slot ceilings?

What feature of the Lithonia troffers addresses this issue?

What makes the RT5 design suitable for both screw slot and standard grid ceilings?

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.
