There are several types of standard electric door openers that can be used to automatically open and close the door. Some of these options are:

Electric door openers with a chain or belt: These openers use a chain or belt to open and close the door. They are easy to install and can be easily added to existing doors.

Electric door openers with a screw: These openers use a screw to open and close the door. They are often stronger and more durable than chain or belt drive openers, but they can be more difficult to install.

Electric door openers with a sliding bar: These openers use a sliding bar to open and close the door. They are often quiet and smooth to use, but they may be less sturdy than other types of openers.

Barrier openers: These openers are specifically designed to open and close barriers. They are often stronger and more durable than other types of openers, but they are also often larger and more expensive.

It is important to consider which type of electric door opener is best suited to the specific needs of your door and the area where the door is located. When choosing an electric door opener, it is also important to consider how easy it is to use and how sturdy and durable it is.
