## Questions & Answers

**Q: The door still squeals / squeaks after I replaced all 4 wheels. I tried wd-40, but this didn't help. Any ideas on how to stop the squealing noise?**
A: wd-40 original is not really a lubricant, try so WD-40 silicon spray or some graphite spray, or any grease.

**Q: Do these rollers fit any screen door or do you have to use the same one you take out**
A: U need to use the same type or style as you  took out

**Q: Do these rollers work on Pella screen doors?**
A: Yes they do. I have Pella sliding doors and used them on the screens.

**Q: What size screw is used to keep tension on this part near the screen?  We are missing these screws.**
A: Don’t know the exact size but I used a flat head (pan head) sheet metal  screw as the screen door hole was worn and bigger than the hole in the tension wheel. It’s been working ever since.
