Abstract: An explosive release window grille system for the window of a house or building. It has a window grille formed from a plurality of laterally spaced vertical bars that are rigidly secured in a grid-like structure by a plurality of horizontal bars. The bottom ends of the vertical bars have an eyelet loop formed in them and a bottom horizontal bar passes therethrough and functions as a shaft about which the window grille can pivot outwardly and downwardly. The opposite ends of the bottom horizontal bracket are secured to the outer wall surface by mounting bracket assemblies. The top horizontal bar has its opposite ends secured to the front wall surface by explosive release bracket assemblies. Each of these assemblies include exploding bolts having an explosive charge mounted in their shank. The bolts are inserted through the wall from the inner surface and their tips are captured by the brackets mounted on the outer surface of the wall.
