Automatic Door Closer

Our automatic door closer offer unmatched quality and longevity, and we can work with our customers to provide custom a variety of door closers to suit any application. While people most likely have seen and noticed an ‘automatic door opener’, many wouldn’t be able to accurately describe or explain its function. If your having trouble imaging what this hardware looks like, imagine a door in an office or school that has a small box with has two arms that connect and form a hinge that moves as the door opens towards the top of the door.  These are also common in our life. Usually placed at the bottom and come with a washer on one of the arms to allow those using the door to prop it open for lengths of time. These are automatic door closers.  different types of automatic door closers include internal automatic door closers that are inside the door, the frame of the door, or at times, even the floor. Foot traffic, style of door, and where the door leads to will all impact which type of automatic door closer is best for said door.
