10 Frame Double Screen Board

A double-screen board is about 1-inch deep with an opening in the center. The center opening is covered with screens on both sides so that bees on one side of the board cannot contact bees on the other side of the board. It often comes with openings in the rim that can be toggled open or closed. Can be used for requeening or splitting hives. Also known as a Snelgrove board.
