The wood door closer's task is to silently ensure that all interior doors close and lock safely and smoothly every time they are opened and then used. This is a requirement so that heat escapes through them less, noise pollution is prevented from escaping outside, dust does not float inside by getting in via an open crack under the door and more security for home or building. The closers consist of a pivoting shaft within an electromechanical cam that causes springs to force these wooden barriers into place every time they swing open until you stop it completely so it won't swing all on its own due simply natural air resistance acting against smooth surfaces like painted drywall and sealed hardwood floorboards, also keeping energy efficient.
