## Questions & Answers

**Q: Does this help fix a gap of 1/2”?**
A: Most likely will. Mine is almost 1/2 inch gap

**Q: how is it installed?**
A: It slips into that slot around the door, just pushes in.  Please forgive the laity but just goes to show you how easy it is to install, I’m clearly no Mr fix-it and managed.

## Customer Reviews

### ⭐⭐⭐⭐⭐ It fits.
*by W***H on June 2, 2022*

It fits and works well

### ⭐⭐⭐ Good but not great
*by A***A on February 26, 2023*

These work well, as long as you don't mind continuously putting them back on the door as the magnets are not strong enough to hold onto the door and so the stips randomly "fall off"

### ⭐⭐⭐⭐⭐ Good product
*by J***H on August 3, 2019*
