Livestock Handling Whip Flags are used to help move and/or sort livestock safely and humanely without having to handle them. A Whip Flag is a 12- by 13-inch nylon flag attached to a flexible 50- or 60-inch fiberglass shaft with a golf-club-grip handle. Double-stitched and coated for added strength and to prevent fraying, the flags are lightweight (less and a pound) and come in assorted bright colors (i.e., red, blue, orange, green, gold).
