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 and because the shield mounts directly to the Stopper Station it is ideal for use when space is limited. As all STI protective covers, this Stopper Station Shield is backed by a three year guarantee against breakage in normal use. It is also highly cost effective and easy to install.
