Is it possible to install the Run-Chicken Automatic Coop Door horizontally instead of vertically?

We do not recommend installing the Run-Chicken Automatic Coop Door horizontally. We have tested a horizontal installment and found it to shorten the lifespan of our product, as over time, the product becomes unstable and unreliable. It will work in a horizontal position but not well. You also must clean it regularly, especially the side rails, because debris and dust can collect inside that can cause the product to malfunction.
