The decking anchors may have a primary portion and a secondary portion that are operatively coupled together, such as through a fastener. The primary portion may comprise one or more primary projections (e.g., first and second primary projections) and/or the secondary portion may comprise one or more secondary projections (e.g., first and second secondary projections). In a first position adjacent projections may be retracted towards each other. In the first position the anchor may be installed into a cavity of the decking panel. The anchor may be rotated into a pre-installed position, and a force is exerted on the anchor such that the projections contact the webs of the decking. In response to continued force the projections move with respect to each other such that the anchor is moved into an installed position (e.g., the adjacent projections extend with respect to each other).
