Fish tape sometimes called a draw wire or electrician’s snake, is an indispensable tool in electrical work. It’s a long, flexible strip of metal (usually steel or fiberglass) housed in a reel. But what makes it so crucial, and why is it called a “fish tape”? The content is provided by Best USA Tools.
The Core Purpose: Guiding Wires Through Concealed Spaces
Fish tape’s primary function is to route electrical wires or cables through walls, ceilings, conduits (protective tubes), and other difficult-to-reach areas during electrical installations or repairs. Imagine trying to push a wire through a narrow, twisting path behind drywall – that’s where fish tape shines.
How Does Fish Tape Work?
- Feeding: The end of the fish tape is inserted into the desired opening (e.g., a hole drilled in a wall stud).
- Pushing or Pulling: The tape is then either pushed through the cavity until it emerges on the other side, or it’s used to hook onto a pre-fed guide wire or string to pull it back through.
- Attaching Wires: The electrical wires are then secured to the end of the fish tape or the guide wire and pulled through the path the tape has created.
Why Not Just Push Wires by Hand?
Navigating through the maze of obstacles inherent in electrical installations can be daunting. While you could technically attempt to push wires manually through short, straight distances, this becomes nearly impossible in most real-world scenarios. Obstacles like insulation, studs, pipes, and the sheer length of many electrical runs make fish tape a necessity, especially when pulling wire inside of pipes.
Understanding the versatility of fish tape as your wire-pulling companion is crucial for efficient installations.

Types of Fish Tape
- Steel Fish Tape: Traditional and durable, steel fish tape is great for most general electrical work. However, it can rust if exposed to moisture and isn’t suitable for live circuits due to its conductivity.
- Fiberglass Fish Tape: Non-conductive and rust-resistant, fiberglass fish tape is ideal for situations where electrical current might be present. It’s also lighter and more flexible than steel tape.

Beyond Electrical Wiring
Fish tape isn’t limited to just electrical cables. It’s also used for:
- Networking Cables: Running Ethernet or other data cables through walls and ceilings.
- Speaker Wires: Installing home theater systems or other audio setups.
- HVAC: Pulling thermostat wires or other low-voltage control wiring.
- Plumbing: In some cases, fish tape can be used to snake through pipes for minor blockages.
Tips for Using Fish Tape Effectively
- Choose the Right Tape: Consider the length of the run, potential obstacles, and whether electrical current will be present.
- Lubricate: Applying a bit of wire-pulling lubricant can help the tape slide more easily through tight spaces.
- Be Patient: Fish tape can be a bit finicky. Take your time, and don’t force it if it gets stuck.
- Safety First: If you’re unsure, consult an electrician. Working with electrical wiring can be dangerous.
The Origin of the Name
The term “fish tape” likely arose from the similarity of the tape’s movements to a fish swimming through water – navigating through tight spaces, bending and turning to follow the path. While the origins aren’t definitively documented, it’s a fitting and memorable analogy.
Conclusion
Fish tape is an unsung hero of the electrical world. While it might not be the most glamorous tool, its ability to navigate hidden pathways makes it essential for modern electrical installations and repairs. Whether you’re a seasoned electrician or a DIY enthusiast, understanding the role of fish tape is key to successful wiring projects.
