Fail-safe automatic gate locks release when power is removed, allowing the gate to open during a power outage or emergency. Fail-locked locks remain secured without power and require electrical power to release, so they suit applications where maintaining controlled access takes priority.

Automatic gate locks in this assortment use low-voltage 12 or 24 VDC power, with some models offering selectable voltage and others automatically accepting either voltage without field adjustment. Plan for control wiring through the included hookup cord and conduit connection, and confirm the lock’s fail-safe or fail-locked operation matches the project’s access and emergency-release requirements.

Automatic gate locks in this category support face mounting, surface mounting, and weldable face mounting, with brackets that can be welded or bolted to the gate for different installation approaches. These options work with sliding or swinging gates in indoor and outdoor settings, while self-aligning receivers and adjustable mounting hardware can help accommodate gate misalignment or sag.

Choose an automatic gate lock with holding force suited to the gate’s size, operation, and security requirements, with available options ranging from 600 to 2,000 pounds. For gates that sag or do not close consistently, a self-aligning receiver can help compensate for misalignment, while locks designed to operate under preload can help secure gates that press against the lock before release.
