Review on Klein Tools 56250 Wire Marker Book: Easy-to-Use Labels for 1-48 Numbering System by Evan Zurlo

Great item. I used one of these to number all the fiber optic and Cat6 cables in a row of server racks. They are easy to use, provide a unique identification of each cable so you don't have to trace the cables back through the cable system, harness, bundles, etc.: Real time savings, both during installation and in the future when maintenance is required. . I have used cheap and expensive cable label machines in the past and using one of these washers will save you time, a lot of effort and frustration. The only negative I can say about them is that I wish they were numbered to 100 or even 200. I would buy them!
