Abstract: A rebar support is provided through an arm-type apparatus, which may have a plurality of dimensions for different concrete constructions. A tube in the apparatus is slid over an upright support such as a grade stake to hold the apparatus in place. Multiple instances of the apparatus may thus be placed over multiple stakes to hold rebar in the correct position for the grid pattern required to strengthen the concrete in a particular structure. Rebar may then be quickly and securely snapped into notches on the apparatus without tying or extensive training of personnel. In an embodiment different designs of the apparatus are provided with notches designed to fit rebar of different diameters. In another embodiment snap-out tabs in the notches are used so that one design of the apparatus may be employed with rebar with different dimensions. The apparatus may be Y-shaped to further strengthen the arms.
