A form for concrete strike-off has a rigid straightedge assembly and a support coupled to one end of the straightedge assembly. The straightedge assembly includes a grate coupled to the bottom edge of a support bar. The grate extends away from the support bar with a top surface of the grate defining a plane on at least one side of the support bar. In use, a portion of the straightedge assembly defines a reference elevation for concrete strike-off operations.
