Abstract
Two generally flat, spaced U-shaped portions of the lug generally parallel to a first reference plane and each having a bight portion connecting a pair of straight parallel spaced leg portions are joined at the free end portions of their leg portions by two generally flat, spaced straight lug portions parallel to each other and to a second reference plane perpendicular to the first. The lug is formed of a continuously wound resin-impregnated strand of glass filaments. Several such lifting lugs are secured to a tank by resin-impregnated glass filaments wound therearound.
