Product Overview

Steel Sidelite Door Frame for Commercial Applications

Sidelite frames are door frames with glass openings attached to one or both sides of the door opening. The sidelight portion can be partial height of the door opening or extend the entire height of the door. The frame is only the door height. If the frame is greater than the door height, the frame is defined as a transom sidelite frame. Glazing bead (glass stops) are provided with all sidelite frames. Stops install on the inside of the frame to hold the glass in place.
