Abstract
An earthquake-activated shelf security system has two guide rails attached to both sides of a shelf or pallet rack. At least one retainer is moveably constrained to move along the guide rails by a rotating loop located on each end of the retainer. The guide rail has a retainer rest portion and allows the retainer to rest in a prepared configuration without moving down the rail unless acted upon by a shaking event such as an earthquake. A movable backstop may be provided to allow the user to adjust the sensitivity of the system to earthquakes. A mesh net that rolls down may be provided to provide additional security to items being stored on the shelf.
