We use corrugated plastic culvert pipe for access to our septic clean outs. It happens to be 30" diameter, and we have traffic-rated lids that go over the top. The original lids were supposed to be rated at 2500# load. One of those cracked when a 3/4 ton pickup rolled over it. We replaced that with one that was supposed to be "better". It broke too in a similar 3/4 ton pickup event.

The newest lid seems to be much stronger. We will see, but I remain somewhat skeptical.

That said. The culvert pipe has never been an issue WRT load. The lids are another story.

When I was looking at the meter pits made from culvert pipe, one of the manufacturers had instructions saying to add a concrete collar around the pipe to make it traffic rated.  They had an elevation view which appeared to show just a concrete ring around the culvert pipe.  They didn't *sell* a concrete ring, so I wondered if you're just supposed to pour it.  Maybe put in two concentric pipes and pour between them?  That ought to be strong enough to park a truck on.

I'm not saying legs are a bad idea....maybe saves horsing around with concrete.

Yes, some kind of tab to keep it centered.   Perhaps some legs that would go down the inside of the culvert with some small plates on the end for feet to give it some more crush strength.
The legs would not have to be attached to the lid.
Not sure whether to make a hinged lid or keep it simple and cheap.

Some sort of studs on the bottom to position it on the pipe, perhaps?

Yeah actually I just realized that 18" diameter is kind of tight for a coil of OSP fiber.  Do-able, but tight.
I guess the hunt continues.   If you do make something, let us know.

I don’t want to do one that small.  But this is ideal for a smaller handhole.  I really can’t add much value.  Too bad they don’t do a larger one.

Chuck,
The Hancor meter pit doesn't include a lid.  Turns out it's just a pre-cut piece of culvert pipe. The meter pit lids I'm finding tend to be cast iron.  They're heavy and costs hundreds of dollars. Not many plastic options, but I did find this polypropylene unit. List price is $92.  Gives you an 11" dia opening into an 18" pipe.
They also say 'water meter' on them.  Maybe I'd have to grind that off.
If I add $30 for a 2' chunk of 18" culvert pipe I'm at $122 list.
Hypothetically speaking, what could your hypothetical product do for me better than this one?
Asking because I'm interested, not trying to be snarky or anything.

Seems like water meter pits might be a much cheaper option for light duty:

    Baltimore City is in the process of replacing all of its water

    wall corrugated pipe with U cutouts in the bottom but are
    clearly manufactured. Guessing they would be a whole lot

        This is the spec you're looking for. Note that they

        Something strong  but cheaper than a $200 polymer concrete

            I need some my self. Sounds like a worthy project to

                I was making handhole components a few years
                ago.  Not a big money maker.  But handholes are
                simply too expensive.  I came up with some
                alternate designs, like a slice of 36” plastic
                conduit.  Made a lid to go over it. Maybe I ought
                to revisit that project. The world needs lower
                cost hand holes.

                We're looking at doing a neighborhood where we
                have wireless now. Private association of about
                40 homes. The president is also an electrical
                contractor and has helped us on other non-fiber
                stuff in the past. So at least we can get duct at
                his cost. Looking like about 6250 feet of duct
                and 21 or 22 handholes. Probably going to follow
                Chuck Hogg's strategy with 1x4 PLCs in the splice
                cases fed by PLCs at the cabinet. My rough
                guestimates are around $25-27k before putting it
                in the ground or customer drops. We figure we can
                make a business case with a $1k install.

                    On the feed down the road it's $1.80/foot
                    plus the cable.  The contractor is supplying

                    honestlyI don't recall how much of that was
                    labor vs material. We did have to add 4
                    poles, so there's that in the $17,000/mile.
                    And that also includes splice enclosures,
                    switches, optics, switch enclosure, and

                    Does your $1/ft in materials include the
                    actual fiber? If not, then we're very
                    close.  If it does then I have to sharpen
                    the pencil quite a bit.

                    How long are the drops? Labor for main runs
                    cost me about $.75/ft last time I did it,
                    plus around $1/ft in materials. I didn't
                    have to do much make ready though, that can
                    add up quickly. I think my drops cost me
                    roughly $1/ft since I'm doing them myself now.
