🔥 Shaft Door
A shaft door is a specially designed access door installed on service shafts such as lift shafts, cable shafts, duct shafts, and plumbing or utility shafts in buildings. Its primary purpose is to provide safe and controlled access for maintenance, inspection, and emergency servicing of vertical service installations.
A Fire Hydrant Shaft Door (FHC Door) is a fire-rated access panel used to enclose hydrant valves and hose reels inside vertical shafts. It helps prevent the chimney effect, stopping fire and smoke from spreading between floors.
