Necessary because script kiddies are constantly hammering all the locks in the world.

Is it just me or removing any or both of the bottom locks wont work because the bar wont be able to pivot enough to be taken out?

Edit: nvm you can rotate the rod and slide the bar sideways.

Lmao, I can't tell if this is stupid, or genius access control. Like if they had problems figuring out which one of their six employees was leaving the lock open, give them each their own lock!

You usually see these on fields that are co-owned or need to be accessed by several municipalities. Everybody gets their own key but can still have access to the area whenever needed.

Wouldn’t just duplicating the key achieve the same purpose or am I missing something?

Duplicating the key removes some accountability. With this set up you can revoke access to only one person, while leaving the access in place for everyone else. If you had a single lock with six copies then a bad actor getting a copy means you’d have to replace everyone else’s keys

This also means one person can’t take their lock off and replace it with another, and therefore lock out everyone else

One case I've seen this, local PD, Sheriff, city Park District and county Forest Preserve District all needed access. They ech have dozens of hundreds of their own locks keyed the same, so they only need to carry one key, but they all need access to this one gate. If it was only one gate, it would be inconvenient but not too difficult, if it was a dozen shared gates, each with different overlapping agencies and each with their own key, every officer or employee would need a big ball of keys again, defeating the reason behind their keyed alike locks they already have.

ngl, i kinda like this. Want to revoke access to any of the users but can't trust them to hand back their key(s)? Np, just change their lock.

Is a hammer a cosmic ray in this example?

nah I think it's a brute force attack, it takes a several tires depending on if the lock is hard

There are better ways of doing this such as this, or if you value your money, a chain.
