The Vari-Crafts Triple Treat Bird Feeder features two seed tubes that are housed on either side of a standard size suet cage to create an attractive and practical feeder. The feeder tubes are made of 1/4" thick, high-density PVC resin that is perfect for withstanding harsh winters while boasting a combined capacity of 1.5 quarts. Each 3.5" diameter feeder tube has two seed ports. Attract a wider variety of birds by offering two different types of seed and by varying the types of suet or seed cakes. The roof is made of enviro-friendly recycled plastic lumber. Slide the roof up the included hanger for convenient cleaning and filling.
