Invisible Closer Hinge
The SOSS Invisible Closer gives you a fire-rated closer that is totally invisible from either side when the door is closed. When the door is open, you see only the hinge face and links.
The closure rate is completely adjustable with an Allen wrench after installation. Installation can be either inside the door itself or inside the door jamb. The SOSS Invisible Closer is ideally suited for all types of doors 1⅜" thick or more. Recommended spacing is one half of the distance from the center of the door to the center of the top hinge.
