I went through the Hav-a-heart trap in one season fifteen years ago. A Coon tore it up to where the door wouldn't shut right. Bought a Tru-Catch which is a lot heavier duty and it is at least fifteen years old. I fix it to the ground or a wall if its in the barn so it cannot be rolled over and open up.
The tru catch is a simple release and a door that drops straight down. When it is down it is secured with a metal ring on each side.
Here is a link and for $100.00 it is the best trap I have seen.
