  • Opens your gate from your car — no getting out in rain, cold, or dark. The included wireless remote lets you open and close from inside your vehicle or home.

  • Fits standard residential driveways — handles single swing gates up to 16 ft long or 550 lbs. No need for a costly heavy-duty commercial system.

  • Install it yourself in a weekend — all mounting hardware and step-by-step instructions included. No electrician, no contractor, no extra labor costs.

  • Control from your smartphone (optional) — add the MMS100 Wi-Fi module to let in guests, deliveries, or service workers remotely. Open and close from anywhere with the app.

  • Run on free solar energy (optional) — pair with the FM123 or FM125 solar panel kit to power your gate with renewable energy. Cut electricity costs and keep your gate running during power outages.

  • Keeps your family and pets safe — UL325-certified safety sensors stop gate movement automatically on contact with people, pets, or vehicles. No pinch points, no surprises.

  • ⚠️ Not for solid surface gates. This opener is rated for gates with less than 30% solid surface coverage. Solid gates create wind resistance that can overload the motor.
