Western Integrated Materials 300 Series Double Door Frames are engineered for commercial interior applications requiring paired door openings. Built from extruded aluminum, these frames provide a consistent architectural appearance while supporting wider access openings for high-traffic areas. The knock-down frame design allows efficient installation, with snap-on trim that conceals fasteners and provides a clean finished look. The system supports standard wall thicknesses and accommodates a variety of door hardware configurations, including astragals and coordinators. Optional fire-rated assemblies are available, making this frame suitable for commercial, institutional, and healthcare environments.
