Abstract: A chair support for a concrete reinforcing bar is formed from smaller and larger molded plastic elements each in the form of a letter A with diverging legs, and upper cross member, and a lower cross member. The smaller element fits through the opening of the larger element and locks in place perpendicularly to the larger element by interengaging notches in the respective cross members.
