DOS certified steel systems tested to withstand 5 or 15 minutes of simulated “mob” attack. 15-minute models are also certified for rifle-level ballistic rounds. Hardware includes automatic multi-point or two manually thrown locks for exceptional strength and durability. Options consist of various single or double leaf configurations and vision or opaque panels.

Design Overview

ANTI-TERRORISM LEVEL SECURITY where conformance to U.S. Department of State forced-entry / ballistic resistant threat levels is required

ARCHITECTURAL APPEAL the formed, reinforced steel frame provides the look of a commercial hollow metal door and complements modern architectural design

DESIGN FLEXIBILITY numerous cladding and trim options offer the ability to complement other building materials

EASE OF OPERATION the use of high quality hinges results in very low pull forces

DURABILITY structural steel materials and high-quality hardware provide extreme durability and low maintenance throughout the life cycle
