Ouch... 28$? Mmm, I'm sorry Mike but my way is cheaper.... Those zipties are too expensive. I can make a hopper pretty quickly and easily without the metal zipties. Just takes some practice and it's smooth sailing.

I don't know if anyone mentioned, but you can use c-rings as well in place of the metal zipties.

We used them to put together one of our rat cages. Should be over by the hardware cloth area in a farm store. They use them for the hardware cloth to make rabbit cages and such. A lot cheaper, and in my opinion easier than zipties.
