ABSTRACT:
A battering ram for forcible entry through a door has a pointed end with barbs to enable the door to be hooked and pulled outward. The barbs will swing between contracted and expanded positions. This spring biases the barbs to the expanded position. The barbs are conical and define a cone with the same taper as the pointed tip when the barbs are collapsed. One end of the battering ram may have a loop for attaching to a line connected to a vehicle. Also, one end of the battering ram may have a battering plate or may have a bar for prying burglar bars outward.
