The window breakers can be attached between the cap and handle of any ASP Baton. they add less than .75" to the baton length. The three ceramic pins of the BreakAway provide instant entry through tempered glass. For emergency entry through a windshield, punch a large circular pattern with the BreakAway. The ceramic pins will penetrate the glass, making it possible to break out the perforated area.
