This standard 600 lbs (280 kg) magnetic lock provides powerful, reliable security for access control systems in commercial, industrial, and institutional environments. The device operates on a fail-safe principle, meaning the lock disengages and the door unlocks when power is removed, which is a critical safety requirement for emergency egress in most buildings. The lock consists of an electromagnet installed on the door frame and a corresponding armature plate mounted on the door. When energized, it provides a strong holding force of up to 600 pounds to keep the door securely shut. It features a durable anodized aluminum housing and is designed for easy surface-mount installation on both inswing and outswing doors using various brackets (sold separately). Compatible with all standard access control components, including keypads, card readers, and exit buttons.
