Fire Door Retainer Door Closers
Often used in commercial properties, workplaces, public buildings, door closers are mechanical devices that use a metal arm to automatically close entranceways after opening, without slamming them shut. In the case of a fire, they help limit the spread of flames and smoke throughout a building, giving more time to raise the alarm and make a safe exit. Door closers can also be fitted around a home to reduce drafts and regulate the temperature in chillier spots. Many include adjustable swing speeds, allowing for fast or slow closing to suit the environment. Helpfully, they can be installed either above or inside an entranceway – providing flexibility and choice for different layouts.
