A multi-piece hinge pivotably connects a top member and a bottom member. The hinge includes an upper hinge member securable to the top member, a lower hinge member securable to the bottom member and fixable in a frame, a hinge cover secured between the upper hinge member and the lower hinge member, and a spring element acting between the upper hinge member and the lower hinge member. The upper hinge member is pivotable relative to the lower hinge member across a pivot range between a closed position and an open position. The pivot range is limited by a stop assembly. In the closed position, the spring element is positioned to bias the upper hinge member toward the closed position, and in the open position, the spring member is displaced over center to bias the upper hinge member toward the open position.
