ABSTRACT:
A U-shaped frame is secured to a pair of spaced fence posts, and the frame has yoke members which secure the U-frame at the top and the bottom to the fence posts. A one-way gate or turnstile is provided by rotatable members on the U-frame having turnstile arms. A means of removably securing the U-frame to the fence posts is in the form of members securing the fence posts which can be manually tightened. The entire turnstile is designed to be readily removable from the fence line or readily insertable in a fence line; if the fence posts to which it is attached are weak, the U-frame tends to strengthen them.
