SOSS 218 Invisible Closer Hinge, Fire Rated, 1-3/4" Door

Product Overview

SOSS Invisible Hinges will never need adjustment The moving pivot point remains inside the hinge during travel, eliminating an external pinch point on the back side of the door. When closed, the SOSS Invisible Hinge cannot be seen or tampered with. When open, the riveted hinge pin is non-removable. The SOSS Invisible Closer gives you a door 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. Installation can be either inside the door itself or inside the door jamb. Can be used on hollow metal, sheet metal, tin clad, steel composite or wood core swinging type fire doors and fames with 20 minute ratings. Use at least one fire-rated closer for every 20" of door height or portion thereof, or one closer for each 55lbs. of door weight or fraction thereof, whichever calculation demands more closers.
