This Bust-a-Cap rescue tool fits the popular Maglite, replacing the existing cap on either the standard or rechargeable model. It screws securely into place, ensuring that it stays put during use and maintaining the light’s waterproof seal to protect the electronics from liquid. The steel head’s narrow point and broad body shatter vehicle or building windows with a single light tap, so you can rapidly gain entry to or exit from a building or vehicle for a quick rescue or tactical escape. Because so little force is needed, it won’t damage your flashlight.
