Parliament Hinge / Wide Throw Hinge

This parliament hinge, also known as a wide throw or backflap hinge, is a specialized type of hinge designed to provide maximum clearance and a wide opening angle. Unlike standard hinges, the hinge pin is offset significantly from the edge of the hinge plates. This offset, or “throw,” allows the hinged object to swing a full 180 degrees or even more, folding back flat against the adjacent surface. This feature is particularly useful in situations where a standard hinge would restrict the opening, such as in narrow hallways, doorways with obstructions, or gates that need to swing fully open against a wall. These hinges are typically constructed from robust materials like steel to ensure strength and durability, especially in heavy-duty applications like gates. They are commonly used for doors, gates, hatches, and other applications requiring a wide swing.

This parliament hinge (also known as a wide throw hinge or backflap hinge) is designed to allow doors, gates, or other hinged objects to swing a full 180 degrees or more. This is achieved by the hinge’s wide throw, which offsets the hinge pin further from the edge of the object being hinged. This design is particularly useful where clearance is an issue or where a wider opening is required. Typically made of steel or other robust metal.
