This Bust-a-Cap rescue tool fits ASP’s range of popular expandable batons, and is compatible with every model in their existing range. It turns your baton into a valuable rescue and escape tool, capable of shattering glass easily for quick access to or exit from a building or vehicle. The shaped steel head requires just a single gentle tap to break a window, making it suitable for use by almost anyone, with either the strong or weak hand. Because so little force is required, using the Bust-a-Cap will not send shattered glass flying or risk damaging your baton.
