Color coding your tools can be a big help. Color choice can be artistic, functional, or individual.
- Artistic—try World Championship colors: green, yellow, black, red, blue, and white.
- Functional—give each size a different color. So your L-keys are faster and easier to retrieve.
- Individual—make all your L-keys one color, different from your work mates. When all yours are yellow, for example, chances are lower your tool ends up in their box.
Here are the tubing codes. Each size (A thru E) is available in 5 colors (green, yellow, black, red, blue, and white). Each length is 12″ (30cm), enough for many wrenches and experiments!
To order, please choose color and quantity from the selection. Then indicate the size (A thru E) in comments on the checkout page. Price is the same for all 12″ (30cm) sections.
