Antti-Teollisuus to provide e-hinge doors for Icon of the Seas Antti-Teollisuus is to provide all stateroom and crew cabin doors for Icon of the Seas, the new Royal Caribbean International cruise ship under construction at Meyer Turku’s shipyard in Finland. The company will supply between 20 and 30 different door types, with an estimated 4,800 fire doors set to be delivered. The doors will include Antti-Teollisuus’s E-hinge system, which provides a concealed ethernet connection for online locking systems. The ethernet cable is completely covered by the door structure, helping to protect it from possible damage. The door leaf can be removed from the frame without disconnecting the cabling, and the system can be combined with AnttiMarine’s adjustable hinge system. The e-hinge system allows old offline locks to be updated to an online system without changing the existing door leaves or frames.
