SOSS 216ICUS19 Invisible Spring Closer Hinge, Black

SOSS Invisible Hinge model #220IC is ideally suited for most types of doors. It features a spring closer that is totally invisible from either side of the door when it is closed, and you can completely adjust the closure rate with an allen wrench even after installation is complete. You dont even have to remove the spring closer to do it! The model #220IC is flexible too-you can install the spring closer either inside the door itself or inside the door jamb. SOSS Invisible Hinges open a full 180° and are single action. Wood screws included. Installation instructions:Allow one spring closer for every 75 lbs of door weight. Please reference the nomograph (p. 6 of the SOSS hinge spec sheets .pdf download on this page) 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.
