Electromagnets are not at all strong in this orientation of attack. Therefore, as the drawingshows, Securitron's Z bracket should be used with an interference piece which blocks the shearing effect while the strength of the magnet blocks one arm moving while the other is stationary. For this technique to work, the motorized operator must be coordinated which means that one arm must move first to clear the interference piece before the other arm starts moving. Gate operators can normally accompli
