Splitting the Jamb
The baseball swing is an excellent forcible entry technique for wood doors set in wood frames, common to most private dwellings. By swinging the halligan like a baseball bat and driving the pike into the jamp you essentially split the frame. Splitting the frame will compromise the keepers on the frame which the bolts of the locks are set. Once the point is set firmly into the frame pressure can be applied to the tool and the door to complete your entry. A great single firefighter technique when faced with a wood door set in a wooden frame.
