This small steel hinge pair has a spring embedded into its spine. This gives each hinge more strength. The spring construction also works like a stop hinge. The spring will not allow the wings to fold backwards or go beyond 180 degrees. There is a patented date stamped on the hinges: “Nov. 16, 1886.”
Each hinge measures 1 1/4 inches vertically and 7/8 inch across both wings. Each wing is 3/8 inch wide.
This pair is ready to be used. Screws are included.
