Hinge Types

Bi-Fold Hinges

Bi-fold Hinges are two hinges of various lengths that are multi-leaf allowing the door or panel to be opened in both or the same direction. Bi-fold hinges have multiple pivot points that allow a tighter swing with a greater degree of travel.

Butt Hinges

Butt hinges are generally 6 inches in length or less. Most commonly used on doors, fabricated panels, etc., this hinge has two rectangular metal plates with screw holes joined by either a pin or rod. It is most commonly used in multiples of three or four. While most in the U.S. are made of steel, butt hinges for exterior doors are made of brass, stainless steel, or aluminum to prevent corrosion.

Case Hinges

The case hinge is a decorative butt hinge. It is most commonly used in suitcases, briefcases, and the like.

Concealed Hinges

This type of hinge is also known as an invisible hinge. These hinges are made so you only see the surface of the door. They consist of two parts, which are pivots and brackets. Concealed hinges commonly used on furniture doors (with or without self-closing feature, and with or without dampening systems).

Continuous Hinges

This type of hinge is also known as a piano hinge. Continuous hinges run the entire length of the door, panel, or box. Continuous hinges are manufactured with or without holes. These hinges also come in various thicknesses, pin diameters, and knuckle lengths.

Custom Hinges

Custom Hinges are any style of hinge manufactured to a customer’s specific needs or requirements.

Flag Hinges

A Flag Hinge can be taken apart with a fixed pin on one leaf. Flag hinges can also swivel a full 360 degrees around the pin. Flag hinges are manufactured as a right hand and a left hand configuration.

Gate Hinges

Gate hinges are a shorter hinge with longer leaves commonly used on fencing.

Heavy Duty Hinges

Heavy duty hinges are made of various hinge styles used in heavy duty applications. These material thicknesses range up to ¼” (one quarter inch) thickness.

Hospital Hinges

Hospital Hinges are commonly shorter in length typically manufactured of stainless steel with rounded machined knuckles.

In-Stock Hinges

Knife Hinges

The Knife Hinge is shaped like a pair of scissors. It is commonly used in toolbox lids as a side support.

Latch Hinges

Latch Hinges combine a hinge and a latch in a standard piece of hardware. They may or may not include a spring release. The Latch Hinge / Spring Release hinge has either a pair of spring-loaded handles or a single handle, which pulls toward the center to release the body or door from the keeper. An alternate style relies on an engagement hole or slot in the adjoining surface. Installation is simple and inexpensive using screws, rivets or by welding. All styles are manufactured to close tolerances. End play and side play are held to a minimum, insuring a precision fit and smooth operation.

Off-Set Hinges

Off-set hinges offset the pin pivot point of the hinge. Off-setting is a secondary process that can be applied to many types of hinges.

Overlay Hinges

Overlay hinges fold into each other, which reduces overall thickness.
