Security device
摘要:
A security device for personal property at a beach includes two rods of a particular construction to permit ready mounting in loose soil or sand. A bar is formed to be attached readily between the two rods, so that neither rod can be turned to remove. A chain is secured at one end of the bar which prevents removal of the bar, and a padlock secures the chain to an item to be protected.
