Keep your existing Troyer's SuperGourd cool during the warmest months using this Troyer's Birds' Paradise Vented Gourd Replacement Cap. This durable, threaded plastic cap replaces a traditional gourd cap for your existing purple martin SuperGourd (not included), for use during the hottest months. A PVC elbow in the center of this plastic cap angles downward, directing hot air out of the cavity to keep the roost comfortable. Heavy-duty polyethylene with ultraviolet inhibitors forms a lasting cap, and its fully opaque design stops light from reaching the nest. Ribs on the outside edge of this cap not only match the canopy of your existing SuperGourd; they are also spaced to the width of a human thumb or finger for a fantastic grip. The elbow twists to always angle downward, and the white color throughout the item aids in keeping it cool. Maintain the temperature inside your existing martin SuperGourd with this Vented Gourd Replacement Cap. Made in the USA.
