The new ADOR2 has a 20" tall opening by 12.5" wide. With a stronger motor it is nearly impossible to pry open. In most all ways it is like the ADOR1 but it is 29" tall and add 15.5" when the door is up/open (44.5" tall), and 13.5" wide.
Read about the ADOR1 and you will learn most of what you need to know about the ADOR2. The ADOR2 runs on nominal 6 volts. We recommend a 6V rechargeable battery.
The ADOR2 usually ships within a few days of order but please call for availability if you need to.
