USAutomatic Sentry 300 Series Dual Swing Gate Opener
The Plug N Go design of all installed components and the easy-to-understand Sentry control board make this the simplest gate opener for the do-it-yourself installer. Typical installation time is under one hour.
The Sentry 300 automatic gate opener is powered by a 12-volt DC battery (not included). This battery is charged by the supplied transformer, which requires AC power (120 VAC) to be located either at the gate area or within 1,000 feet of it. If the AC power is more than 10 feet from the gate opener's control box, additional extension cable is required.
The automatic gate opener's solar charging method is optional and requires the Sentry solar panel kit (sold separately) for proper operation. Typically, only one panel will be required. The Sentry dual swing gate opener is capable of a high number of cycles per day. For information on what you can expect from a solar-charged system, see the solar charging section of this site. Any accessories added to your gate opener must be solar-friendly and will be identified as such. Review the solar region map to determine the number of cycles per day you can expect from a solar-charged system.
The Sentry 300 control board features high-quality components and industry-leading innovations, such as auto-resetting fuses for motor protection. The outdated auto-type fuse that blows and must be replaced has been eliminated from this controller to avoid the unnecessary expense of purchasing fuses. Another patent-pending feature of the control board is the onboard potentiometers for adjusting stop limits.
The Sentry 300 Series Swing Gate Opener by USAutomatic is proudly manufactured in the US.

Gate Crafters has actual experience.
We have a testing area, we have factory and internal training courses, we build gates and have our own gates that are automated, we attended all industry trade shows in multiple countries and are a member of the AFA, and we pay visits to our chosen manufacturers' factories. All these factors are what have lead to us having so many exclusive additions. When you see and actually use as many products as we have you tend to have many ideas for minor changes that have major impacts. We acted on these ideas and have utilized them to help thousands of customers automate their gates.
The following tools and supplies are suggested in the manufacturer manual for optimal installation. They are not provided by Gate Crafters, however, most tools are available at local hardware stores for purchase or rental.
- Wrenches - 7/16, 9/16 and 10mm
- Sockets 7/16, 3/8 and 5/16
- Drill
- Drill bits 1/4 and 3/8 inch
- Drill adapter for socket attachment
- Pliers
- Hack saw
- Level and tape measure
Welding is the recommended method of securing the linear actuator mounts to the gate and hinge post. Bolt on brackets are provided and are acceptable but may require frequent service to keep tight. They must be very securely attached (i.e. carriage bolts with lock nuts and washers). Lag type bolts are not recommended. Loose or unstable linear actuator mounts will result in improper operation. Please refer to the Installation Manual for Tools Needed. Depending on the type of gate, power supply and contributing environmental factors additional tools or supplies may be needed. Please review the product manual associated with this gate opener model for further details. |
