ABSTRACT:
A fire-rated light kit for a fire-resistant partition includes a track for holding a window pane in an aperture of the partition. The track includes a channel for capturing an edge of the window pane, and a flange. A first intumescent material is positioned under the track to seal between the track and the partition. A second intumescent layer is positioned on top of the track. A flammable molding material can be positioned over the flange of the track. In the event of heat or flame, the second intumescent layer expands and pushes the flammable trim away from the glass and/or partition.
