ChickenGuard Self-Locking Chicken Coop Door Kit
This "kit" doesn't include the motor. It's just the door. So there's nothing "self-locking" about this. You have to purchase the motor separately. What a joke! The "kit" should include everything not just a door. I'm so annoyed that I wasted my money on this.
This has made life so much easier! Already had the auto opener, and now installed this door. Was pretty simple to install and operates perfectly.
