A Google search shows a number of products that are suitable. Note that if the pool shell is conductive or if there are bonded parts such as ladders that have 9 square inch of surface area in contact with the water, you do not need any special fitting.

We have used several of the Burndy kits on above ground pools that required it.

[h=2]Perma-Cast PB2008 Water Bonding Fitting[/h]It's a brass fitting that gets placed directly into the pool plumbing at the equipment. It has a lug on the outside for the bond wire.
It is supposed to be always immersed in water to complete the bond. PermaCast suggests an irrigation box that gives access to a plumbing pipe below grade.
If your pool equipment is below grade already, I generally place it after the filter pump before any chlorine feeders or chlorine generators.
We build concrete pools and will never use the surface skimmer set up. It's only accessible by breaking up the concrete around the skim.
With the fitting in a corrosive condition constantly, it will rot away at some point.
The inline mentioned is accessible for servicing and actually exceeds the code with more square inch surface area.

I've used a stainless steel plate that mounts inside of the filter box just on the side of the pool, found it on the Internet. It has a stud that a hole needed drilled thru the box for and came with a lug. Worked really well, and I was just there a week ago and no leaks.

The one you mention is set inside the surface skimmer. I read your post and saw filter box. Hate to be correction king in regards to pool terms, the filter is the tank set adjacent to your filter pump at the equipment pad.
The surface skimmer is at the pool side collecting debris from the surface. That's where this product is set.
If this type was the only choice, a vinyl lined pool or a fiberglass pool it would readily accessible as it there is no concrete poured around it.
On a concrete pool, the surface skimmer is surrounded by concrete. To replace, one must break up the concrete to replace it. Big PIA job.

It is very common to make electrical connections in concrete, if you use the correct fittings they are not going to rot away.

Sorry, I am referring to the skimmer box on a above ground pool.

I don't think the connection at the skimmer would be imbedded in the concrete but actually below the surface of the deck. You would have to bust the deck up though to access it.
I'd look at doing some sort of irreversible connection if you're going to bury it.

If the fitting is marked DB, which it should be if it is made for that I fail to see any issue with burying it.
You have to DB many pool connections to the bond.

On new concrete pools, we form a "box" of wood (2by's and plywood) 2' x 2'. The plastic surface skimmer is set in this box. During the gunite process of shooting concrete, the box is filled with concrete encasing and supporting the surface skimmer. There is generally 8'-10' of concrete surrounding it. So, to replace the skimmer bond set up, we would have to bust out some concrete to access.
On a vinyl lined pool or fiberglass this is not the case. The bond connection as far easier to access.
As I had stated in an earlier post, my concern is that this type will be something exposed to corrosive conditions of chlorine, low pH levels and salt form chlorine generators. In a concrete pool when they rot away, and they will, it will be a chore to replace. This is why I prefer the inline brass fitting.

It is common. When bonding to the rebar, the bond lug is encased in concrete. They are designed for direct burial.
Incidentally, concrete is not acidic but very basic, which deters corrosion.
We have demod old pools to find the original rebar in good shape.
