Timely® Classic Prfinished Steel Sidelight Frames are designed for commercial, institutional, and multi-family construction requiring door openings with one or more sidelights. These configurations allow natural light transfer while maintaining a unified frame system for both door and glazing. Manufactured from hot-dipped galvanized steel, these frames provide corrosion resistance and long-term durability in demanding environments. The prefinished design enables installation after wall finishes are complete, reducing labor and eliminating field painting. Sidelight configurations support a range of glazing options, widths, and mullion layouts while maintaining compatibility with fire-rated assemblies where required.
