    1. I’ve used a contraption just like this touring a rural home with some acreage for sale and it works!

    2. Far simpler to replace the main rod with a piece of chain and then just chain the rest of the locks together

      I’ve seen someone do something similar with padlocks on a farm gate – each lock becomes a link in a chain. You need a key to open an existing lock, then add your own padlock and voila! You have access via your own lock to whatever the lock-chain is securing.

      Peak Facebook content.

      The caption is usually “which lock releases the steel rod? 9/10 people get this wrong!”

      Not that interesting

    5. Well. In my project, I use this method for safety procedures. 2 engineers, 3 safety officers, 1 expert, all have their own padlocks for loto.

    6. Yeah they should definitely invest in some sort of electronic key fob system . This was a joke, plz don’t crucify

      Haha! This is commonly used as an example of logic gates for computer programing 101z

    8. 15 and 18 I’d be annoyed having those, looks like it takes extra effort to remove the metal plate.

    9. This is very common on ranches although I’ve mostly seen it in a wheel configuration. This one seems needlessly complicated to me (when I takeoff my lock, there’s a chance I’m now holding up to 4 individual and usually weighty pieces of metal).

      The reason you don’t just have one key is that there’s several people that are accessing the land and this gives the owner control over who gets access and when. For example, you could have several hunters with leases on the property, an oil and gas company that needs to access their wells, several ranch hands, construction crews, etc. The owner can now select which locks to have on the gate therefore giving or removing access as they’d like

    10. Why not use same key? I see these used at cell towers. Multiple contractors can access many sites using “their” common key. Saves everyone from carrying 100s of different keys.

      I don’t see how 15 and 18 will achieve anything by removing the lock
