## Questions & Answers

**Q: Where do I buy The Screws for cover?**
A: We do not sell the screws separately but the ones that are sent are #10x1.5" stainless steel screws. I believe they are Hex head but you can use the screw head of your preference. Please let me know if you have any other questions.

**Q: Will this cover work for a 15" inside Diameter non corrugated pipe?**
A: When using this cover outside of its main purpose I would consult the manufacturer's technical specification to see it it will work in your application: https://www.polylok.com/sites/default/files/300415-C15''%20cover.pdf
Although the cover is designed to fit pipe with a 15" inside diameter you may not have any surface area to screw it down if not using corrugated pipe.
