What brand is it?

Hmm..As far as I know- There is not a locking device. There are products for commercial sites that lock but they are much larger and are not made of plastic. Unless someone else here knows of solution, I would take grass clippings and dirt and cover the lid so it is not as visible.

maybe a stainless security screw would work, you know the ones that have an allen hole with a little post to prevent the standard allen wrench? get a round head one that pliers won't work on, it's doubtful that anyone would go to the trouble to source the wrench I think...

Many valve boxes (including 10" rounds) can come with what is called a "lockable" lid. The lock is just an angled bolt that stops the lid from being lifted. It is turned into place with a wrench.

I would not, under any circumstances, bury a valve box so it can not be found. We put valve boxes around things for a reason... so we have access to items for service. Burying a box is a guarantee of future headaches.

To the orignal poster: Do you reason to be concerned with the possibility of someone with bad intentions opening the valve box? Just asking because in my years of professional experience, I've never once encountered a customer with an issue, including large scale commercial sites where vandalism is a concern in general.

If valve box security is such an issue, replace the round box with a Ametek rectangular box, which is made with locking snaps built into the lid. (which many installers routinely remove, because the boxes are a royal pain to open without the special tool they never seem to have handy)
