8 Biggest Locks on Earth

July 29, 2011

Today we have to deploy increasingly sophisticated measures to secure our possessions and deter would be thieves. Past decades have introduced key cards, number pads and Total Recall style biometric scanning.

As these more advanced security measures become further integrated into our everyday lives we would like to present the collection below as a reminder that, sometimes, the best form of protection is great big lump of reinforced steel.

Location: Lenoir City, Tennessee, USA

Constructed: 1908

Weight: 22 lbs

The B. Quad-M 11 3/4″w x 5 was the largest and heaviest time lock Yale ever produced; often used as part of the largest vault doors. The sides were purposefully left open so the customer could observe the intricate inner workings of the lock. Its size is an aesthetic rather than technical choice. Vault doors had begun to increase in size and these steel leviathans could not be seen to depend on a dinky time lock mechanism. Beautifully finished and pattered, this piece is a testament to an age when considerations of prestige trumped the bottom line.
