Shaft Doors

Shaft doors are doors that are designed to be used in vertical shafts, such as elevator shafts, stairwells, and ventilation shafts. These doors are typically made of metal and are designed to be strong and durable, as they must be able to withstand the pressure of the shaft and the weight of the objects that pass through them. Shaft doors are usually equipped with safety features, such as emergency release mechanisms, to ensure that they can be opened in the event of an emergency.
