SOSS 418SSIC Invisible Closer Hinge, 316 Stainless Steel with Fire Rating

The SOSS 418SSIC Invisible Closer Hinge is engineered for doors 1-3/4" thick and constructed of complete 316 stainless steel for exceptional corrosion resistance and durability. This single action hinge opens a full 180° while remaining totally invisible from either side of the door when closed. The closure rate is completely adjustable with an allen wrench after installation, without requiring removal of the closer, and installation can be completed inside the door itself or inside the door jamb. Underwriters Laboratories labeled, the 418SSIC carries fire ratings of 20/90/180 Minute depending on door construction and material.
