Product Details

Western Integrated Materials 300 Series Sidelight Frames are engineered for commercial interior applications requiring door openings with adjacent glazing. These configurations allow natural light transfer while maintaining a unified 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 range of sidelight configurations, glazing options, and hardware requirements while maintaining compatibility with fire-rated assemblies where required.
