Electricians Tools (fish tape, bits, tone testers)
If you're in the business, you know Greenlee is the preferred brand in fish tape reels. They slide nicely, the loops don't give-out on a tough pull, and the steel fish tape doesn't seem to ever kink the way the other brands do.
We also carry some pretty handy testing equipment (see category at left). From Fish tape to line locators, Arizonatools.com has the electricians tools you need.
