Abstract
This invention relates to grab irons and more particularly to two-piece, adjustable grab irons. The grab iron consists of a handhold-shape containing a mounting flange portion and a rod member as well as a grabfoot-shape containing a mounting flange portion and a base portion having a ring with a hole sized to receive the rod member of the handhold-shape. The rod member possesses a series of holes that are spaced along at least a portion of the rod member, and are formed at the same angle as measured from a horizontal vector. The base portion has a single pin hole having a size and angle that permits alignment with any of the pin holes in the rod member. The two pieces are secured together by the use of a metal fastener such as a steel expansion pin or a screw that is placed through both the pin hole in the base member and the appropriate hole in the rod member. The excess portion of the rod member extending past the grabfoot-shape is cut off. Furthermore, the base ring hole is formed by drilling or casting the grabfoot-shape, producing a torus shaped base portion, and resulting in a secure fit between the rod member and the base portion ring.
