Modular Building Applications

Each Kirncroft anti-vandal shutter is designed and physically checked to make sure that there is a 4mm (3/16″) tolerance between the doors and frame.  This built in tolerance ensures that in the event of a modular or portable building “racking”, the shutter will operate with full functionality.
