The Adhesive Fingersafe Door Safety System Complete Set is designed to fully protect both sides of the hinge area of the door. (Pieces are also sold individually if a child only has access to one side of a door, e.g., an office or closet). Features a commercial-grade adhesive for a simple peel-and-stick installation—no hardware needed. Full installation instructions are included with every order. (Please note: Due to the adhesive application, this system is not UL rated or fire door safe). This product will fit wood, aluminum, metal, stainless steel, and UPVC doors and will allow the door to operate in excess of 180 degrees. It can be modified to accommodate doors or gates with a maximum opening of 16″ (wider openings up to 8.5 inches / 21.5cm). Can be easily cut to size on site with metal shears. Constructed of high-quality PVC with TPE hinges. Durability: U.V. and high impact resistance. Easily cleaned with common household cleaners. Accidents happen, so we offer replacement parts for the push-side adhesive guard: Replacement Accordion Panel.
