Don't forget the mighty Greenlee Adapt-o-matic Coupling Adjuster - lets you use any coupling on any raceway (as long as it's the same size). (I know it's not a tool, technically, but I felt the need to include it).

Had to change mid-run from 3/4 MC to PVC then to AL Rigid down the way - Without that Adap-o-matic, I'd have been fishing couplings out of the truck for hours!
