That box thing at the top of the door is leaking oil. Thats a call we receive from time to time. That box thing is a hydrolic door closer. Its been around for over a 100 years. The main job of the door closer is to control the door. Good quality door closers control the door opening and closing. When you pull the door open you wind a spring. The spring unwinds to close the door. The hydrolics controls how fast the door closes and that closing speed is adjustable with valves.
A door with out a door closer can be dangerous. Wind can pull the door open and damage hinges. The door can slam and injure some one in the way of the door. Most all exterior doors should have a door closer. Door closers can also act as a security device. Doors with access control need to self close every time to guarantee the door locks. The Lock Pros, Inc supplies and installs quality door closers. Please call us with any questions.
