The Tomahawk Excluder One Way Door E80 and other excluders must be mounted or set horizontally to function properly. If the excluder were vertical with the mounting wings on the top, the door would fall open, allowing the animals to re-enter.
We have checked with the manufacturer and they offered the following advice for attaching the E80 Excluder. You can put up boards or heavy hardware cloth found at a local hardware store around to make the gaps go away. Then attach the excluded flaps using wire/hardware clips or staples.
Tomahawk Excluder One Way Door for Raccoon and similar sized animals Model E80 has a spring to keep raccoons from opening the door back up. Â
