Their US Automatic Sentry gate opener system is probably their most popular platform, and far and away one of the most complete and reliable systems ever produced – by any company.

Leveraging high quality construction materials, smart engineering, and almost two decades of experience, it’s easy to understand why so many people choose to protect their most important properties with this kind of tech…

… It just flat-out works!

If you’d like to learn a little bit more about these electric gate opener options, hopefully you’ll pay close attention to the inside information we have for you below.

Let’s get right to it!

What separates US automatic from the rest of the competition?

The US Automatic company first started engineering designs for their automatic gate opener and electric gate opener solutions way back in 1994, though they didn’t go into full line production until early 1995.

This means that they’ve been in operation for nearly 20 years, and have been able to establish themselves as one of the most trustworthy and reliable manufacturers on the planet.

A very much forward thinking company, they were one of the first automatic gate opener and electric gate opener manufacturers to consider engineering low-voltage and solar powered gate operating systems, and have worked to pioneer a number of other groundbreaking technological advances as well.

Each and every one of their control boards leverage high powered microprocessors that offer unparalleled “juice” right out of the box, but also allow for robust modification and the expansion of new feature sets with little headache or hassle whatsoever.

On top of that, all of their products are manufactured right here in the United States of America, and they live and die by their reputation.

This is the kind of company that people feel perfectly comfortable moving forward with, the kind of company that enjoys almost unparalleled respect and admiration in their industry – even from their competition!

What’s so special about the US Automatic Sentry 300 S commercial grade automatic gate opener?

There’s a lot to like about the US automatic gate opener system (“Patriot gate opener”), and we’re going to try and break down a number of those advantages and big benefits below.

The first would have to be the fact that the entire platform is constructed to be as close to “set it and forget it” as humanly possible. The control board of this automatic gate opener is already assembled and ready to be “plugged into” nearly any automatic gate opening system with very little modification whatsoever, shortening installation time and eliminating a lot of headache and hassle in the process.

On top of that, the entire system takes advantage of solar power regeneration and battery charging, which means that it can operate on renewable energy sources only – though it’s recommended that a 12v DC battery is plugged into the system as a backup or for nighttime operation.accessories_sm_solar

And that doesn’t even begin to scratch the surface of the truly amazing high quality construction components and materials that are used throughout this system. Zero corners are cut anywhere across the board, but instead high quality construction materials and properly executed engineering procedures are followed to the letter – resulting in a solution that is heading shoulders above all others.

And what’s inside the box?

Well, there are a number of different US Automatic gate openers that you could end up purchasing that would dictate exactly what you find in the box when you purchase one of these units, but the overwhelming majority of these electric gate opener solutions will include:

  • The actual Sentry 300 S control board ready to be mounted
  • All of the necessary mounting hardware to get your system installed
  • A commercial grade swing gate opener with universal adapter
  • A 100% watertight junction box and wire nuts
  • 50 feet of cable
  • And a dedicated instructional manual to clearly outline exactly how to get your Sentry 300 S system up and running just as quickly as humanly possible

Now you see why there are so many glowing the positive Sentry 300 S gate opener reviews out there, and why so many people choose to go forward with this solution in this solution only – pretty much ignoring any other options on the market today.
