Polecat

 Is an amazing lightweight rigging tool that uses a spring loaded system to expand like a wall spreader, but cannot hold the weight of a wall spreader.  Which is usually around 50 lbs.  A Polecat is rated for 10 to 20 lbs.  They come in varying lengths.  2’ to 4’, 4’ to 8’ and 8’ to 16’.  I love using them for corners of rooms, I actually use them from the floor up to the ceiling and you can then clamp your light in a much sleeker profile than having a stand that might be in the shot.
