Series 300 Security Mullions
The ultimate security partner for both 3700 Rim and 3600 Vertical Rod devices, these removable mullions are made from steel-reinforced aluminum. A simple removal system for easy in, easy out convenience and matching anodized finishes make them the right choice for pair-of-doors applications. Easily cut for a perfect field fit, these mullions come with heavy duty strikes and are available in sizes up to 9 feet. Color matched security clips provide an added level of security overcoming the natural twisting of the door stile under pressure.
