The Brinsea ChickSafe Advance Automatic Chicken Coop Door Opener gives you ultimate control over your chicken coop’s door without even having to get out of bed. This opener will automatically open and close your coop’s door based on the changing light levels. It’s also equipped with a digital control panel so that you can program a clock timer to override the light-driven system. Decide just when you’d like your coop door open or closed, or use the weekend “lie-in” feature if you want yourself (and your birdie friends!) to sleep in. Suitable for use with a vertical sliding or hinged door, this opener is super easy to install. Just secure the control box to the coop with the included screws and tie the lifting cord to your door. There’s no manual calibration to mess with, and the opener will automatically adjust itself to work with the height of the coop’s door. Weatherproof, made with UV materials and featuring just one moving part, this opener is durable and reliable. It’s capable of opening doors that weigh up to eight pounds. It’s also equipped with an auto-stop feature to keep your birdie friends safe in case they’re blocking the door. This opener is a fantastic way to know that your flock is safe when you can’t be home to open or shut their coop yourself.
