I had to move a security camera and was left with an exposed hole in the soffit. I couldn't find anything to cover the hole so I designed this. Unlike most other caps, this is designed to work with a fairly broad range of hole sizes. It should also work even if the hole is not round. Wrap a thread around the winged nut to hold it in place until you get the screw started then pull the thread out and tighten the screw/cover in with a small flat blade screwdriver.
