FAAC 770 In-Ground 24V Swing Gate Operator
The FAAC 770 Underground Swing Gate Operator operates as a concealed, 24V DC actuator. It is designed for underground installation to preserve gate aesthetics. It supports gates up to 1100 lbs and 11 ft, making it suitable for mid-to-large residential and some light commercial gates. The non-reversing mechanical design helps secure the gate without external locks in many installations, and IP67 protection ensures reliable operation in wet outdoor environments. The installation is service-friendly, with components including the operator, underground support box, mounting hardware, and installation instructions. Best for buyers who want a hidden, durable option with straightforward maintenance and standard 110° opening angles, with optional 140° or 180° kits available.
Who it’s best for: Homeowners prioritizing a discreet look, gated communities, and small commercial properties where gate aesthetics matter. Consider this if you have a gate leaf up to 11 ft and need a robust underground solution.
One caution: Ensure proper underground trenching and backfill meet local codes to avoid water exposure risk, even with IP67 protection. Accessibility to the unit for service should be planned without removing the gate leaf.
FAAC S800H ENC CBAC In-Ground 100° (108720)
This in-ground hydraulic swing gate operator uses hydraulic actuation for powerful, smooth movement. It supports gates up to 1760 lbs and 13 ft, designed for larger residential, condominium, or commercial swings. The 100° opening version focuses on standard underground installations with precise encoder control for reliable positioning. IP67 protection makes it suitable for underground installations in harsh outdoor environments. Included components typically cover the operator, integrated underground assembly, mounting hardware, and installation instructions. Best for installations where hydraulic strength and precise encoder feedback are critical for consistent gate performance.
Who it’s best for: Installers or homeowners with heavier gates who want robust hydraulic power and precise positioning without external mechanical stops. Choose this if you need strong performance with a narrower opening angle.
One caution: Hydraulic systems may require more installation attention around seals and venting; ensure compatibility with your gate design and local maintenance capabilities.
FAAC S800H ENC CBAC In-Ground 180° (108722)
The 180° version extends opening range for wider driveways and gate configurations, still using in-ground hydraulic actuation. It shares the heavy-duty capabilities of 1760 lbs and 13 ft, with integrated encoder control and built-in mechanical stops for reliable operation. IP67 protection supports underground use and exposure to moisture. As with other FAAC underground models, installation includes underground assembly components and mounting hardware. Best for properties that require maximum gate clearance and future-proof expansion to wider openings.
Who it’s best for: Properties with wide driveways or gates that need broad swing arcs; ideal for newer installations seeking long-term reliability and minimal visible hardware.
One caution: Plan for a possibly longer installation time due to hydraulic routing and underground integration needs.
LIAMOS Gate Opener, Underground Swing
The LIAMOS unit is described as an underground swing door opener that uses a rotating arm driven by a DC motor. It supports 90° openings in one direction or both directions, and the motor shell is designed for waterproof, corrosion-resistant operation. This system is suitable for indoor and outdoor use and includes two controllers with an English debugging interface and multiple functional interfaces like electric locks and backup batteries. Best for buyers seeking a compact underground option with dual-control capability and simple installation.
Who it’s best for: Small to mid-sized residential gates where a discrete underground solution is desired and where two-way operation is helpful for limited space setups.
One caution: Ensure the system’s opening angle and power requirements align with your specific gate dimensions and local electrical codes.
Ghost Controls Solar Heavy-Duty Gate Opener Kit (TSS1XP)
This solar-powered kit is designed for single swing driveway gates up to 20 feet and 900 pounds. It includes a gate opener arm, control box with a control panel, remote transmitters, brackets, mounting hardware, a 10-watt solar panel, and a battery harness. It’s celebrated for not requiring electrical wiring on-site, making it easier to install in locations without reliable power access. IP67 protection supports external use, and the system offers a long remote range up to 1000 ft with a 12 V battery as the required power source (not included in the kit). Best for off-grid installations where solar power is preferred and installation flexibility is important.
Who it’s best for: Homeowners seeking a solar-driven, remotely controlled gate opener for medium-sized gates where trenching and hard wiring aren’t ideal.
One caution: Solar setups depend on sun exposure and battery capacity; performance may vary with weather and seasonal changes.
Buying Guide: Underground Swing Gate Opener Essentials
- Gate size and weight: Match the operator’s rated capacity with your gate’s weight and leaf length. Heavier gates require hydraulic or robust electro-mechanical systems.
- Opening angle needs: Consider 100°, 110°, or 180° configurations. Wide openings are helpful for large driveways but may require extra space and installation planning.
- Power and installation: Underground models demand trenching, weatherproofing, and reliable electrical or battery backups. Solar options reduce wiring needs but rely on sun exposure and battery maintenance.
- Environmental protection: Look for IP protection ratings (IP67) for underground and outdoor use. Consider local moisture, temperature, and soil conditions when choosing hydraulic vs. electromechanical.
- Control accessibility: Encoders and mechanical stops improve positioning accuracy. Remote range, app control, and security features may influence daily use.
- Maintenance and serviceability: Choose units with accessible service points and clear installation instructions. Underground components should be inspected for moisture ingress and corrosion resistance.
Frequently Asked Questions
- What is an underground swing gate opener? A gate opener that operates the gate leaf from below ground level, hidden from view, to preserve gate aesthetics.
- What gates can be powered by underground operators? Typically large residential gates up to about 1100–1760 lbs, depending on the model, and varying leaf lengths up to around 13 ft per leaf.
- Do underground openers require professional installation? Most installations benefit from professional experience due to trenching, alignment, and wiring considerations, though some models offer user-friendly components for easier setups.
- Are hydraulic underground openers better than electromechanical ones? Hydraulic systems provide strong, smooth motion for heavier gates, while electromechanical options are often simpler and more cost-effective for lighter gates.
- Is IP67 protection sufficient for underground use? IP67 provides high-level protection against immersion and moisture exposure, which is generally suitable for underground installations when installed correctly.
- Can I mix a solar opener with an underground system? Some kits support solar power; ensure compatibility with the gate’s electrical requirements and battery backup for reliable operation.
