Abstract: The security apparatus and kit, as well as the method of using them, includes a security device or cradle for receiving and restraining equipment, to be protected. Adhesive material extends along and is affixed to a substantial portion of the underside of the device, and forms a bond to the upper surface of a supporting surface. A restraining arrangement of the device surrounds a portion of the portable equipment to be secured, which includes a lockable arm which moves between an opened and a closed position to permit the equipment to be received and retained lockably within the device, and yet be readily unlocked and opened by authorized personnel. In order to remove the security cradle from a supporting surface once it has been bonded adhesively thereto, a dispenser of releasing agent cools the adhesive material to disable temporarily its adhesive bond, and permit the apparatus to be bonded subsequently to another surface.
