## Questions & Answers

**Q: Any idea as to the diameter of the spline?**
A: The spline comes in various sizes. To match my purchase to the spline I was replacing, I used a drill gauge to measure the old spline and then ordered the appropriate size. If you don't have a drill gauge, you can take a sample of the old spline to Lowes and try and match it up with the spline they sell there.

**Q: what is the id of this product?**
A: great replacement product. works excellent

**Q: Is it truly .250 dia most everyones elses is .220 dia and measure so??**
A: Mine was within .010 of .250 throughout

**Q: What size should I get for an average window  screen that needs to be replaced talking about diameter ?**
A: Next size smaller.  This was too big for regular window or door.
