FYI: The connectors that this tool is designed for are ONLY used in telecommunications and other low voltage applications like alarm and intercoms.
They are made by 3M and are almost always filled with petroleum jelly to ward off moisture in outdoor environments. They are also expensive; that is why hardly anyone uses them except for cable splicers at the local telco - and are often hard to find.
The specifications say the length and width and height of these pliers are all 0.39 inches. Do they come with a pair of tweezers to hold them?
