Anti Theft Devices


Fed up with replacing or recharging misused fire extinguishers? Here is an effective way to stop such theft and vandalism! This stopper uses a time-tested, steel-cable-operated switch mechanism. It allows the extinguisher to be used for fire fighting at any time, but sounds a piercing alarm when the extinguisher is moved from its normal position. Easy to install and fits all fire extinguisher models. Its highly visible "stop sign" design is a deterrent itself.

Also an extremely effective way in letting every one within an mediate area know that there is a fire happing and a fire extinguisher is been taken to be used.
