If a cable breaks, the fall safety device will prevent the door blade from falling down. The Compact Door is provided with two independent steel cables with a safety factor of 6. If a cable breaks, the falling door blade will be caught in the side rail and hold it in place.
This standard feature on every Compact Door prevents undesirable uplift of the door blade from the outside. Because of this round the clock automatic locking system the door is well protected against forced entry.
