The steel cables that carry the Compact door have a safety factor of six. In the unlikely event of a cable breaking the door is stopped from falling by fall safety devise, consisting of little hooks on the foot brackets. These grab in to the side rails preventing the folding door from falling unexpectedly.
How it works
The fall safety device prevents the door blade to drop in the event of a cable snapping. Hooks will grab in the side rails and stop the door.
