Prime-Line Products Prime-Line N 7273 Bi-Fold Door Hinge, 3 in., Steel, Satin Nickel Plated, Non-Mortise (Pack of 2)

These bi-fold door hinges are constructed of steel and come in a zinc plated finish. They feature a non-mortise design allowing them to be easily mounted on the door’s edges, avoiding the need to chisel and mortise for installation. For best results, use a 3/32 in. bit to drill pilot holes prior to screwing in fasteners to avoid splitting wood. These door hinges are used on bi-fold doors by many wardrobe door manufacturers.
