Garage Door Spring Safety - 4 Cables Vs Anti-drop

Should a component fail, safety is paramount.  On sectional garage doors, the door is lifted by cables connected to the lifting springs. Should a cable fail, the door must be prevented from falling to be certified safe.

CarTeck extension springs are held by four cables as standard, two at each side of the door. Other manufacturers' doors, that use torsion springs, employ an anti-drop brake. Both are safe, but one creates real practical problems if a cable fails.

With CarTeck’s four cables, should a cable fail, three remain. Three cables are sufficient to safely close the door. The homeowner can then make a service call and a repair can be planned, in the meantime, the garage is safe and secure.

When a cable brakes on a torsion spring door with an anti-drop device, the brake engages, the door stops functioning and is locked in position. It leaves customers making an emergency repair call and their property at risk because the door can’t be closed.

In the very rare event of a cable failure, CarTeck shows its exceptional qualities – safe and practical too.
