Western Integrated Materials 300 Series Transom Frames are engineered for commercial interior applications requiring door openings with glazing above the door. The transom configuration allows natural light transfer while maintaining a consistent aluminum frame system. Manufactured from extruded aluminum, these frames provide durability, corrosion resistance, and a clean architectural appearance. The knock-down design allows efficient installation, with snap-on trim concealing fasteners and improving alignment. The system supports standard wall thicknesses and accommodates a variety of glazing and hardware configurations while maintaining compatibility with fire-rated assemblies where required.
