The 1st AUTOMATIC Earthquake Cabinet Latches! These latches are designed to allow unhampered access to your cabinets and remain inactive until the movement of an earthquake triggers it to lock the cabinet doors automatically, instantaneously. Slamming the cabinet door of a well-secured cabinet will not activate the SeismoLatches, which allows normal daily use of cabinets. Each latch can withstand pressure up to 50 lbs. (approximately 50 china plates). Perfect for use in homes, offices, hospitals and labs.
