ABSTRACT:
A locking device for preventing access to a bolt or stud-nut which secures an equipment to a base. The device comprises three parts: a rectangular tube body, a slide member and a lock body. In use, the bolt is put through a hole in the tube body and the equipment, and tightened down. The slide member is then inserted in one end of the tube and slid over the head of the bolt or stud-nut and the lock body is inserted in the tube and locked by a key. This prevents the slide from being removed and prevents access to the bolt head or stud nut. The device is flat and compact, and may be used for a variety of applications where equipments are secured by bolts or stud-nuts, particularly in tight quarters.
