STI-6545-G Mini Stopper II without Horn with Spacer - Green

This unique and patented device has been helping stop false fire alarms around the world for more than 25 years, without restricting legitimate alarms.

Mini Stopper II consists of a clear, tamperproof, super tough polycarbonate shield and frame that fits over manual pull stations. Cover contains no horn, has a blue housing and spacer. Designed for surface mount units, spacer has knockouts for exposed conduit. Additional models are available with a built-in warning horn that sounds when cover is lifted to gain access to the pull station (see STI-6600).
