ABSTRACT:
An architectural rail system usable in doors, windows, and building walls for supporting and framing panels. Hollow aluminum rails are formed with internal ribs that form tracks for the slidable reception of ballistic steel strips or panels. The rails are thus structurally and ballistically reinforced against penetration by small caliber projectiles fired from rifles and/or pistols. The rail panel-framing system is useful where security against armed attack is a consideration, e.g. in banks, cashier stations at movie theatres, area ticket windows, fast food restaurants, etc.
