How To Coil an Extension Cord

Improper extension cord storage can lead to tangled messes and damaged cords. Learning how to properly coil and store your extension cords will save you time, frustration, and money in the long run. Here, we explore expert techniques for coiling extension cords and provide tips for safe storage. This Old House general contractor Tom Silva and host Kevin O’Connor put these proper cord management techniques into practice in the video above.

The Importance of Proper Cord Management

Implementing good cord management practices will help you maintain your tools and work more efficiently. Proper cord management is important for several reasons, including that it:

• Extends cord life
• Prevents tangles and knots
• Ensures safety by avoiding damaged wires
• Saves time when setting up for projects
• Keeps work areas organized and tidy

Common Mistakes in Cord Storage

Before diving into the best practices for coiling extension cords, it’s important to understand what not to do. Many people make these common mistakes when storing their cords:

Using Cord Reels That Wind Too Tightly

While cord reels may seem convenient, they often wind cords too tightly. This can lead to several issues. It puts stress on the internal wire, creates a “memory” in the cord that makes it difficult to lay flat, and may cause damage to the cord over time.

Securing Cords With Tape

Using tape to secure coiled cords is another common mistake. This practice can:

• Leave behind a sticky residue on the cord
• Make it difficult to unwind the cord quickly
• Potentially damage the cord’s outer casing

Plugging Cord Ends Together

Some people plug the male and female ends of the cord together for storage. Silva warns against this practice, which can damage the internal wires, puts unnecessary stress on the plug connections, and may lead to electrical hazards.

The Over-and-Under Technique To Coil Extension Cords

The over-and-under technique is the preferred method for coiling extension cords among professionals like TOH gaffer Kenny Boyle, who shared this tip. This method helps prevent tangles and allows the cord to lie flat when it’s in use. Here’s how to do it:

1. Hold the cord in your non-dominant hand.
2. Use your dominant hand to grab a section of the cord about arm’s length away.
3. Twist the cord over, creating a loop.
4. Slide your hand down the cord.
5. Create the next loop by twisting the cord under.
6. Continue alternating over and under until you reach the end of the cord.

This technique may take some practice to master, but it’s worthwhile. The over-and-under method keeps your cord tangle-free and ready for your next project.

Securing the Coiled Cord

Once you’ve coiled your extension cord using the over-and-under technique, you’ll need to secure it for storage. Below are some safe and effective methods.

Use a String or Velcro Strap

Attach a small piece of string or a Velcro strap to one end of the cord. After coiling, wrap the string or strap around the middle of the coiled cord. Finally, tie a simple knot or secure the Velcro to keep the coil intact.

This method is great because it’s gentle on the cord and easy to remove when you need to use it.

Create a Cord Wrap

For a built-in solution, you can create a cord wrap. This method means you’ll always have a way to secure your cord without searching for separate ties:

1. Cut a small piece of leather or durable fabric.
2. Punch holes on either end.
3. Thread a string or elastic through the holes.
4. Attach the wrap to one end of the cord.
5. Use it to secure the coiled cord when not in use.

Creative Cord Storage Solutions

Proper storage is just as important as proper coiling. Here are some innovative ways to store your extension cords.

The Bucket Method

This clever storage solution keeps your cord tangle-free and easy to access:

1. Use a drill and a 2-inch-diameter hole saw to bore a hole in the side of a 5-gallon bucket.
2. Pull the male end of the cord through the hole.
3. Coil the rest of the cord inside the bucket.
4. When ready to use, set the bucket near an outlet, plug in the male end, and pull out as much cord as needed.

Wall-Mounted Storage

For a more permanent storage solution, consider wall-mounted options. You might install heavy-duty hooks or pegs on your garage or workshop wall, use pegboard systems for customizable storage, or mount a dedicated cord storage rack.

Portable Cord Organizers

If you frequently transport cords, try these tips:

• Use cord wraps or spools designed for extension cords.
• Invest in a cord carry bag with separate compartments.
• Buy cord straps that allow you to hang the coiled cord from your tool belt.

Maintenance Tips for Extension Cords

Proper storage is just one aspect of extension cord care. Here are some other maintenance tips to keep your cords in top condition:

• Inspect cords regularly for signs of wear or damage.
• Clean cords with a damp cloth to remove dirt and debris.
• Store cords in a dry place to prevent moisture damage.
• Avoid running cords under carpets or across high-traffic areas.
• Use the appropriate gauge cord for the intended use to prevent overheating.

Advanced Tips for Cord Management

To take your cord management to the next level, consider these advanced tips for maintaining and storing your extension cords.

Using Cordless Drills for Quick Coiling

A cordless drill can be an excellent tool for quickly coiling your extension cords. Attach a small hook to the end of the drill and let it twist the cord as you hold it in place. This method not only speeds up the coiling process but also creates uniform loops, making storage more manageable.

Labeling Your Cords

If you use multiple extension cords for different purposes, labeling can be a time saver. Use a piece of tape or a label maker to mark the length and intended use of each cord. This practice helps you quickly identify the right cord for each task, reducing setup time and avoiding untangling.

Heat-Shrink Tubing for Added Protection

If you frequently use your extension cords in rough environments, try adding heat-shrink tubing to the plug ends. This tubing can provide additional protection against wear and tear, extending the life of your cords. Just slide a piece of tubing over the plug connection and use a heat gun to shrink it into place.
