Description of E-Clip Tool Set - 4 Piece - OTC 4492: Enhancing Product Visibility for Efficient Searching
Dual operation tool. One end of tool releases e-clip while the other end of tool installs e-clip. Tools fit four sizes of e-clips 6mm 7mm 8mm and 9mm. Each tool easily locks into the handle provided.
As far as I know they are sold with "e" clips but I have tried using them with "c" clips. Didn't work at all. I have no problem removing and installing the "e" clips so they end up in the trash.
