About Hinges

Clean Room Hinges

Keep environments free of contaminants—plastic bushings on these metal hinges prevent metal-to-metal contact that can release particles as hinges open and close.
Hinges with a quick-disconnect pin make it easy to remove your door from its frame. These hinges come in two parts—one for the door and one for the frame—that you join and take apart without any special tools.

Hold-Closed Half-Mortise Concealed Cabinet Hinges




Spring tension pulls the door closed when it’s open less than 10° and keeps it closed without a catch or latch. Also known as European hinges, only one cutout (mortise) is needed to mount these hinges. Once mounted, the hinges will be completely hidden from the outside when the door is closed. They are commonly found on washroom and kitchen cabinetry. All of these hinges have a nonremovable pin to deter tampering. Hinges with a quick-release clip allow easy door removal.
Hinges for overlay doors are for doors that cover their frame.
Hinges for half overlay doors are for doors that cover half of their frame.
For Style 1 hinges, mount the frame leaf to the inside cabinet wall and mount the door leaf into a recessed cutout (mortise) on the inside of the cabinet door.
