From the 2016 National Hardware Show, Las Vegas.

When is a lock, not a lock?

Not A Lock is designed as a theft deterrent with the appearance of a locking padlock, but surprise -- it does not lock! Just like folks who have security system signs outside their house and no security system installed, or have fake security cameras, Not A Lock offers the look of a heavy duty lock while not needing keys, combinations, Bluetooth, etc. Not A Lock snaps closed like a locking padlock, but opens with a sharp pull-down. Randall, from EKUSA, the company that makes the lock said think of it as using a gate locking latch, except the gate locking mechanism is inside the heavy-duty padlock. I think this is a great idea to guard things that aren't expensive, but you like to guard with some sort of security without having to worrying about losing the key, carrying an extra key, or not having the key with you. I think it's a clever idea, probably the most inventive thing I saw the 2016 National Hardware Show.$14.99.
