We recently supplied and fitted 2 complete 3m x 4m high security roller shutter doors. They provide the convenience of easy access, but with the reassurance of security as they are more robust than the standard 'up and over' garage doors. The operation of the shutters can be interfaced with existing automatic gate radio fobs. The compact shutter rolls onto the cylinder, mounted above the opening, to give full access. Many safety devices are available including pressure strips, safety beams, strobes, sounders etc, and radio control operation comes as standard.
