SOSS® Invisible Hinge model 220IC is ideally suited for most types of doors that are 2'' thick. The model 220IC is made of zinc and steel materials. Nylon links provide added strength and durability. The SOSS Invisible Closer gives you a 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. The Underwriters Laboratories labeled the model #220IC SOSS Invisible Hinge can be used on hollow metal, sheet metal, tin clad, steel composite or wood core swinging type fire doors and frames with a 20 minute rating. Allow one closer for every 55 lbs of door weight or portion thereof. Fire Rated applications also require one fire rated hinge for every 20'' of door height or fraction thereof. The calculation that requires more hinges is the total number of hinges required. Recommended spacing for use of one spring closer is half of the distance from the center line of the door to the center line of the top hinge. Please reference the hinge spacing drawing.
