Review: Super happy with this. I've been updating my camper as a DIY project and changing the white exterior plastics etc. over to black for that more modern look. These fit into place, replacing the original like a glove and were easy to hook up. No issues whatsoever. Why would I pay double or triple, when I can get these?! No brainer. Highly recommended!

A: No screws are not included.

**Q: Can this replace an identicle already installed one without anything else needed?**
A: Yes, but you will need to use a good sealant around the outer flange.
