How to Choose a Heyco® Strain Relief
- and Make the Right Choice

To specify a Strain Relief and get the best fit, ask yourself the following 4 questions:

1. Is my wire or wire harness Round or Flat?
 
Most Heyco Strain Relief tabular charts are segregated into "For Round Cables" and "For Flat Cables."
2. What is my wire or wire harness Diameter or Dimensions?
 
Heyco Strain Relief charts are typically sequenced by Wire Size / Mounting Hole Size.
3. What is my panel Thickness?
 
A. Lockit Strain Reliefs - Multiple Locking Step “Fingers” provide a Finished Fit across a wide spectrum of Panel Thicknesses
 
B. Original Strain Reliefs - the Maximum Panel Thickness provides the best Finished Fit.
4. What Functionality and Assembly Method do I need?
