What if the hole is not a perfect circle?

Tell us the shape and send a photo. We plan an outline to match.

Does the cap need to hold water out?

Tell us that up front. A tight seal on any part is not something we can promise, but we plan the closest fit we can.

Can I get a flanged cap that sits flush?

Yes. Tell us the flange diameter and thickness you want.
