Hang your SuperGourds on the Purple Martin SuperGourd Rack System. This gourd rack system is absolutely top-of-the-line in construction, materials, and innovative design.  It features a four-part pulley system for easy raising and lowering; twelve 3/8” high-strength aluminum arms with 90-degree-bend gourd mounts; a polyester rope; an aluminum rope cleat; and a 2-inch-square aluminum pole assembly with a plastic pole cap.  Square poles are superior in strength to round martin poles.  Gourds slip on and off the arms quickly and easily, and anchor with stainless steel spring clips.  The gourd arms slip easily in and out of the all-aluminum, pre-assembled hub, which has nylon glide tabs for squeak-free operation.  Arms will hold up to 12 gourds (sold seperately).
