Abstract: A general purpose target for defining a window in space is provided by an F shaped frame having spaced parallel vertical ribbons extending between opposing horizontal arms of the F shape to define a strike zone. One of the ribbons may be removed to enable a bat to swing through the strike zone. The frame may be elevated when the window in space should be higher, as for an archery target, for exmaple. A colored sleeve may be disposed on each horizontal arm to define the width of the strike zone. The F shaped frame may be yieldably mounted by a spring on a support stand, or the frame may be rotatably mounted in the stand, to bend or rotate when struck by a thrown ball or swung bat.
