SOSS Invisible Hinge model #218IC is ideally suited for all types of doors. The SOSS Invisible Spring Closer gives you a spring closer that is totally invisible from either side when the door is closed. The closure rate is completely adjustable with an allen wrench after installation, and does not require removal of the spring closer. Installation can be either inside the door itself or inside the door jamb. SOSS Invisible Hinges open a full 180° and are a single action hinge.
