Got it today in the mail it requires roughly 29" I don't have that available. The Ador1 requires 28.5" BUT....can I install the Ador1 upside down? My coops elevated off the ground so upside down would work. I already framed in the hole for the door and there's only about 24" above the door before the gables from the roof.
Mendozer, yes I think upsidedown would work as long as you secure the battery with sticky-back velcro to keep it secure. But I have another idea now. I could send you a magnet that you could glue to the panel 4" above where the lower magnet is on the panel. That will stop the upward motion 4" below and limit the total height to 24", so should fit below your gable. The trade-off is that the opening for the chickens to pass through will be reduced from 13" high to 9" high. The opening area would be 9" x 10.5" which should be enough for chickens. If you compare that reduced opening size to the opening size of a competing automatic door selling on Amazon for $329 you'll see that this reduced size is still bigger in area that this $329 door (which is 10"x8.25"). BTW, since I brought up this other door, I don't see any advantages of this expensive competing door -- what is it supposed to offer for the additional $130 compared to the ADOR and some other doors out there that are $100 less? ...maybe that's why it is what they are calling it: "Incredible Chicken Door". Hehehehe. ...the price is incredible.
So I don't think it will be a bad trade-off to do this trick with reducing ADOR's motion by 4"s -- instead it should solve your problem. Please call me if you want to try this idea. --ROD
