Concealed door closers automatically close your open doors, even if you don't close them yourself. Most door closers have a swinging arm mechanism that gently closes the door if it is left ajar. Installing a concealed door closer is a process that simply requires you to drill a few holes into your door frame, but you must first find a door closer that fits.
Measure your door using your tape measure. Record all measurements, including height, width and depth.
Check the weight of your door by consulting the manufacturer's installation manual. If you don't have a manual from the door's manufacturer, consult the professional who installed the door for the door's weight specifications. If you cannot contact the person who installed the door, have a professional contractor check your door and provide you with a proper weight rating. The weight of the door is important, as concealed door openers have specific weight limitations.
Measure the degree of the door opening by opening the door as far as it will go and measuring the amount of degrees it opens with an angle measuring tool. Note which direction your door opens (left or right), as door closers only close in one direction. When selecting a door opener, choose a model that closes in the opposite direction from how your door opens. If your door opens to the left, you need a door closer that closes to the right, and vice versa.
Purchase a concealed door closer that can fit on your door, handle the weight of your door and handle your door's degree of opening. Consult the packaging of the door closer for these specifications. If you are unsure whether you are selecting a proper door closer, ask your local hardware specialist to assist you. There are three main types of concealed door closers: regular arm, parallel arm and top jamb. Regular arm models are most commonly installed on the bottom side of the top of your door frame and attach to your door with a single arm. Parallel arm models are installed on either the top of the door or the side of the door where the door is attached to the frame and lie parallel to the frame of the door. Top jamb models are mounted to your door frame and attach to your door with a single swaying arm mechanism that closes your door.
Install the door closer by following the manufacturer's instructions.
