Double Locking Bi-Fold Hinge is the answer to bi-fold door problems!
It automatically locks flat in the open position so the door remains straight and can engage magnetic or friction catches when the doors are folded to eliminate "bounce-back."
It has 3 positive stops. It locks at 0°, 180°, and 135°.
The hinge measures 2 1/2" wide x 2 9/16" high x 1/8" thick, for minimum stile width of 1 1/8". It is countersunk for #6 screws.
The hinge is constructed of die-cast metal with a Nylon and Brass Plated Steel spring mechanism. It has a Dark Brown Powder Coated Finish.
