Safetybrake Ltd now markets Roller Shutter Doors and Grilles incorporating the industry's first and only progressive anti drop safety device. The device was developed by our sister company Cambridge Door Services (which has been supplying roller Shutter doors since 1987) in response to the Product Standard BS EN 13241-2003 which calls for the balancing system to be safeguarded against uncontrolled movement (i.e. spring failure) Our unique safetybrake device can detect if the spring breaks and also when the spring is becoming weak and requires attention. Should the spring break the door will be arrested. No other company can offer such a device as this and our Safetybrake device offers the only true solution to today's regulations.
