This inexpensive and highly durable cover was created to mount directly onto STI’s Stopper® Station buttons. When ordered with a Stopper Station, the push button shell will have two notched slots for mounting the shield. The shield takes hard knocks in stride while protecting the button against vandalism, damage or accidental activation. Because the shield mounts directly to the Stopper Station, it is ideal for use when space is limited. Cover is highly cost effective and easy to install.
