Form a martin colony in your own backyard or add to your existing one with the Purple Martin SuperGourd Rack Starter System without Gourds.  The STAR-ter rack features a 2-inch-square, high-tensile strength aluminum two-piece pole that is 12.5 feet tall above ground when installed.  The gourd hub and arms accommodate 8 gourds, and raise and lower with a 2-pulley rope & pulley lanyard system(included).   Pre-installed nylon glide buttons in the hub assure squeak-free operation.  The aluminum gourd arms attach to the hub using stainless steel hardware.
