This seed block holder is a model for efficiency and simplicity. Just slide seed cylinders onto the sturdy steel EZFeeder and hang. The birds will love it; they are not limited to a few seed ports so it is common to see a dozen birds at once on this feeder. A little hook at the bottom of the feeder allows you to hang a suet basket, tube feeder, or even another EZFeeder below your feeder. Seed cylinders can last up to five times longer than loose seed so you are saved the time and trouble of filling the feeders every day. Constructed of sturdy steel with a hunter green powder-coat finish. Size 8.5” x 12”.
