Forcing entry through a locked wood checkrail or double-hung window is best accomplished by prying at the top of the lower sash. This location is optimal because it allows for effective leverage against the locking mechanism while minimizing the risk of damaging the window itself or the surrounding frame. The top of the lower sash typically provides a better angle to apply force, facilitating the movement needed to disengage the lock.

When applying force at this point, the pry tool can adequately engage both the sash and the frame, allowing for easier entry. If an attempt were made at the bottom of the lower sash, it could be more difficult to overcome the locking mechanism due to the design of the window. Meanwhile, prying in the middle of the frame or at the side of the upper sash may not apply sufficient force directly to the locking mechanism or may even damage the window, causing an unnecessary complication. Therefore, selecting the top of the lower sash enhances the probability of successful entry while reducing potential damage.
