They located on the upper floor in the tool department. I have not bought them myself, I just saw them there. I would open the boxs there and make sure they are the right size.

I haven't tried them myself yet. I had already bought some. But they were cheaper then the one I got. When (not if;) I change my cage I will be sure to go to Sears!
