A pair of hooks to hold the first frame in a bee hive, to make more space when inspecting. The short hook goes over the hive edge, with the cutouts facing outwards to allow you to get your fingers under the top bars to easily pick the frame up again. Fits National and 14x12 hives, and maybe WBC. Probably too wide for Commercial or Langstroth (try ckcampbell248's much more elegant design instead).
