Here’s how you master-key a gate without the complications of master-keying the padlocks. Anyone with a key to one of these locks can open the gate…
I love how the rest of the hikers have taken off and left my friend Zeke Wolfskehl behind while he checks out the locks. A good door-photo is worth the risk of days spent wandering alone in the wilderness. 🙂

Fishing lease access!!!
I’ve seen this, and it always makes me giggle. Thanks.
Nice idea, but in reality, many people are not smart enough to put locks back where they belong. They end up bypassing one or more of the other locks and locking out certain groups or people. We have had to make complicated devices and use chains to make sure that locks won’t fit in the wrong place. Even if you make the chains just long enough to fit with all the locks in place, they still find a way to mess it up. The best we were able to do in a similar gate was to make a bunch of short 4 link chains and separate the locks with them and make the entire loop only big enough to do the job with no extra length.
We’ve been doing that on jobsites, securing the gates through the temp fencing, for years.
I’ll take your padlocks and raise you a bar.
This is the access gate to our warehouse..

love it!!
Self made or for sale somewhere online???
It came with the warehouse when we bought it. It’s got a sticker that says “StymieLock” out of Charlotte NC. We added the blue cuff.
I like this thing. Too bad the vertical /cane bolt latch isn’t UNDER the horizontal bar to keep it from being raised. Some double gates could be loose enough to still be pushed/pulled open with this arrangement.
Mike,
That is a great idea! And it wouldn’t be too hard to accomplish. We could just weld a small bar onto the vertical pole, sticking out right underneath the horizontal bar which would prevent it from going up until the horizontal bar was moved. Thank you!
It’s called railroad gating. It allows several entities access to the gate without issuing keys. It’s an old practice and works well when multiple organizations need access to a shared space.
That’s the same system used on the local multi-owner, multi-company fireworks storage area…
Common to see that daisy chain setup around here,

Forgot to add,
I also get many request for the Forest Service, Weyerhaeuser, BLM and other access padlock keys,
just gotta say no…
This is really common practice at many construction sites. Saves having to collect keys when the job is done, and if left unlocked, it’s pretty easy to tell who unlocked it.
This is actually a very common application where multiple agencies, companies or different people need access to a particular area. The power company where I grew up setup their gates to the farms that were in the right-of-way of the power lines. Trucking companies (for dairy milk), the farmers and the power company all had their own padlocks.
I have a similar problem when traveling. (I dig hardware)
