The door that is seen from each Fermator Elevator Doors of a building is referred to as the outer or hoistway door. This hoistway door is a part of the building (each landing). It is important to realize that the car door does all the work; the hoistway door is a dependent. These doors can be opened or closed by electric motors, or manually for emergency incidents.

Safety devices are located at each landing to prevent inadvertent hoistway door openings and to prevent an elevator car from moving unless a door is in a locked position.

The difference between the car doors and the hoistway doors is that the elevator car door travels through the hoistway with the car but the hoistway doors are fixed doors in each landing floor.

Fermator Automatic Doors: Center opening doors consist of two power operated panels that part simultaneously with a brisk, noiseless motion.

Telescopic Door: It consists of two power operated panels that are geared together. One door moves twice as fast as the other door so that both doors will meet concurrently in the open position.

Collapsible Gate: Constructed from double channel rolled pickets 16mm wide x 2.5mm thick interconnected by 6mm thick galvanized steel solid lattice bars.
