Klein Tools VDV226-107 Compact Ratcheting Modular Data Cable Crimper/Wire Stripper/Wire Cutter, CAT6, CAT5, CAT3, Flat-Satin Voice Cable

This was a goal of mine, when we first bought our house. There was no clear path from our basement, where our utilities come in, to our second floor. It wasn’t until years later, when I was replacing our second floor flooring, that I revealed a pass through that allowed for clear passage of wire up to the attic. The main path was running the Ethernet cable through the air return ducts. Running wire through air return ducts isn’t ideal, but you can buy specific rated type of cat6+ cable called “plenum” rated, which has extra insulation for this use case. If you have a clear path room to room, the most challenging part of this DIY might be splicing and crimping your own cable. Bug a good cable crimper. I used this Klein cable crimper, which works great, but it’s still takes patience to get it just right. After you splice and cap each end of the cable, a network tester saves a lot of frustration by ensuring you have a solid connection on both ends.
