ABSTRACT:
A ground anchor for channel posts has an angle iron leg driven into the ground and an upright fin plate or strip secured to the upper end thereof to stabilize the leg against tilting. The channel post straddles the angle iron leg receiving the apex of the leg in the channel thereof and is deformed to spread its legs apart into tight gripping relation with the angle iron. The spreading apart of the legs may be effected by drawbolts which fixedly connect the channel post with the angle iron leg or by a tool applied to the post adjacent the leg permitting the post to enter a socket on the leg formed by the fin plate or strip whereupon releasing of the tool permits the spread apart post legs to spring back toward their free state position thereby bottoming the base of the post in the socket. The spread apart legs of the post tightly grip the angle iron leg. The post may be removed from the angle by releasing the drawbolts or by again applying a spreading tool to free the post from the socket.
