Walmart sells a Fram branded adjustable oil filter wrench, and it is exactly like the Lisle Tools 63600 mentioned in this thread. The Lisle is/was made in USA, and the Fram is made in China. Can't remember the exact price, but the Fram was about $6.00, and it works very good.
For what ever reason, every time I do a search for the Fram filter wrench at Walmart, I can not find it, but there it is in the store every time I go there. I can't find it on Amazon or Ebay either. I am thinking it's some kind of Walmart exclusive.
Anyway, I don't know if this is a deal between Fram and Lisle, or the patent has expired. All I do know is the Fram China made clone works very good, and it costs about half of the Lisle.
