On various calls I have been forced to break either car or building windows. I have used either a Monadnock PR-24 or a Monadnock AutoLock, the former was past issue and the latter is current issue. Neither was designed for this task. I have a scar to prove it.
Bust a Cap, Inc. is a company that manufactures a device that serves as an end-cap to several standard issue flashlights and batons. The cap replaces the threaded end. It is made of special steel that is made specifically for breaking glass.
Bust a Caps, which are made in the USA, are available for Streamlight and Maglite flashlights. They are also made for ASP batons. Because my Autolock has a release button on the tail, it is not compatible with the Bust a Cap.
I was issued a Streamlight Stinger, which I upgraded with a Terralux LED. I purchased a Bust a Cap for my Stinger for under $10 on sale from an on-line retailer. The MSRP is less than $20.
With a flashlight, you must affix the “o-ring” from the original cap on to the Bust a Cap so the light stays waterproof. The Bust a Cap had room for the spare bulb, if you are still incandescent.
In the product photographs provided by the manufacturer, the Bust a Cap’s tip looked awfully pointy. I worried about it puncturing the leather of my flashlight holder. When I received the cap, it was less sharp at the point than in the pictures.
I am very happy add some use to an already existing piece of kit that I carry daily. Our SWAT guys were given inexpensive spring-loaded keychain window breakers. Because it was just one more thing to carry, the keychain ended up riding in my seat bag.
To break a window, the Bust a Cap is tapped firmly into the glass to shatter it. Strenuous force is not needed. Videos on their website show proper application of the cap to a window.
The most likely windows targeted by a Bust a Cap will be car side windows. For these the cap is ideal. It is recommended to wear gloves, long sleeves, and eye protection if available.
I think the Bust a Cap adds a very useful tool to my Stinger. I will offer my personal opinion that in an emergency, if I have to use my flashlight as an impact weapon, the conical tip provided by the Bust a Cap gives a nice striking surface.
The Bust a Cap is inexpensive insurance should you need it. Use safety protective equipment when you can, but at least be aware of the dangers if you have to improvise and use such a tool in an emergency. Click here for my article about types of glass and window breaking.
