Here's the run access door: it's an old cheapo screen door with wore attached instead of screen:
Here's the pop-hole: a sliding door made of thin 1/4" plywood that runs true in tracks made of aluminum angle iron. It slides to the right and we can access it from the other side of that interior wall (hence not have to go into the henhouse) and latch it shut at night. Since the latch is INSIDE the garage, it doesn't have to be racoon-proof so we used a simple hook.
Thanks to both of you. Nugget that is a good close up pic of your run door. The brackets on the inside to support it are a great idea! You both have some VERY nice and clean coops,love the "pop-hole" doors.
