Sargent & Greenleaf doesn't make ordinary padlocks. You won't find them hanging on racks at the neighborhood hardware store.
These are specialized locks, designed for high security applications or resistance to extreme weather conditions. S&G has supplied the world's most rugged padlocks to the US Government for decades and designed to meet stringent US Government specifications, widely used in US and Canadian Federal agencies and military facilities. From munitions bunkers, CIA, FBI, prison to file cabinets containing sensitive information, the name on the padlock has been Sargent & Greenleaf.
