ABSTRACT:
An apparatus for forming risers for concrete steps between a pair of spaced vertical walls. The apparatus takes the form of a bracket which is to connect with a length of wood such as a conventional 2.times.6. A threaded member associated with the bracket in threading movement causes the bracket to extend from the 2.times.6 to produce a clamping of the 2.times.6 in the bracket between the spaced vertical walls. As a result, a removable barrier is formed which is to contain concrete when it is poured. After sufficient drying of the concrete, the 2.times.6 and the bracket are removed from the vertical side walls leaving the now produced concrete step.
