FlexGrate (Flex Grate) Door

I need a door for the FlexGrates I installed on my downspouts. Under even moderate rain, water gushes out the front, and I don't even want to think about what happens if there is a leaf stuck under there that would deflect more. I designed this door to be able to fit inside and swivel out easily. I punched a hole in each side near the top using an awl, it holds it tight enough to prevent the splashing water from pushing it open, but not so tight that you can't open the door to clean out any blockages. I added a version with a small handle so I didn't have to twist the pegs on the side, it works very well.
