How to Pick the Right Fish Tape for Ethernet

Standing in the fish tape aisle is a rite of passage for every first-time DIY cable runner — and it's surprisingly easy to pick wrong. In this episode, we break down the material science hiding behind the packaging: why nylon flat tapes slide over insulation while steel excels in conduit, how a screw-on cable grip protects your Cat6A from damage, and why buying a 40-meter tape for an 8-meter run creates snags. We cover the real cost range ($8 to $50), the string trick for measuring actual path length, and why your network's signal integrity depends on the pull, not just the cable. If you're running Ethernet through finished walls, this is the buying guide you need.
