Passing from a house's living area to the sleep area, the Light door can satisfy every need of an internal door. It transforms the room into a security area, while providing a high standard design. The internal Light security door, due to its hidden hinge, is totally flush with the wall while the wall can be covered with the same material. The hidden hinge, patented by Golden Door, can open at 105 or 180 degrees and due to its construction it can be set in many ways. The Light series allows the possibility of flush frame, both externally and internally, giving a more minimal look in indoor areas.
