How to Identify the Size of Your MCD Shades: 17mm, 28mm, or 32mm Springs

If you're looking to replace or repair the springs in your MCD shades, it's important to know which size you have. MCD shades come in three common spring sizes: 17mm, 28mm, and 32mm. The key difference is the diameter of the spring's round end. Here's a simple guide to help you determine the correct spring size based on easy-to-find household items.

1. 17mm Spring
- How to Identify: The round end of a 17mm spring is about the same size as a dime.
- What to Do: Take a dime and hold it up to the end of the shade’s spring. If they’re nearly identical in size, you’re likely dealing with a 17mm spring.
