Heavy duty run door

[mtnchickens303]

I made this run door to weigh about 30lbs so when its closed its secure. I used a wire cable and a pully system to make it easy to open for us. The coop is in town but I wanted very good critter defense.

That is one heavy door.
I wanted very secure too but went a different route. Mine has an old fashioned like 1400's style slide in board. When the board is there it cannot be raised or pushed in even with great force.
