SOSS® Invisible Hinge model #220IC is ideally suited for most 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.
Allow one spring closer for every 75 lbs of door weight. Please reference nomograph for total number of hinges required. Recommended spacing for use of one spring closer is half of the distance from the center of the door to the center of the top hinge. Please reference hinge spacing drawing for multiple closers.
Machine screws are available for an additional charge.
