Abstract: A rotatable and retractable storage lug (50), especially suited for, but not limited to, nuclear reactor applications is claimed. The lug (50) is equipped with a rotatable and slidable weight-cylinder assembly (76 and 64) in coaxial relationship with a pivoted support beam (60). Furthermore, the weight-cylinder assembly (76 and 64) and support beam (60) are connected together by a lockable channel (70 and 70A), groove (68 and 68A) and pin (62 and 62A) arrangement. By rotating the cylinder (64), the support beam (60) will assume either a horizontal or working position or a vertical or stored position.
