The usual choice for a normal, standard 27-inch (685mm)door, our work-horse, sometimes used with a 12-inch version as the lower hinge if the door looks tall or narrow, or with a third hinge halfway down the door. Traditional practice is use three T-hinges or garnet hinges to stop a door warping in an unusually damp position, like a bathroom. All hinges are priced per pair.
