Nope. You could put one corner of the triangle lid downhole and then the rest could follow. The ONLY shape where it can't go downhole without failure of either the cover or the hole is a round cover.

yeah, think about it a little harder... I guess I should have been more specific- equilateral or a reuleaux triangle.
If there is a cover that is 18.9" on each side, and the hole is 18" on each side, but fits into a recess that is 19" on each side, then it ain't going in the hole... it'll hang on 2 edges of the lid near the corners in 2 corners of the hole.
If the cover and hole were both EXACTLY 18" on a side and 1" thick, it still wouldn't fit if you put a corner in the hole first... because the thickness of the cover will keep the corners from fitting all the way to the corners of the hole- but it could slide thru if you put it in flat (barely, would be a friction fit)

ETA: first pic below was a bad example, above is correct.

Are you trying to tell me if both triangles are removed they won't fall in that hole??

ok, that's a bad example, because they make up a square they can't be equilateral triangles.. one side has to be longer.

I searched for images, and I found that one.... and jumped on it...

but equilateral or reuleaux triangles would work... as long as there's a lip or taper (which there is on round manhole covers, or they would fall in the hole laid flat.)

Yes, it would work.

I suppose the biggest problem would be the corners sticking up since most manholes aren't very flush with the surrounding road.

I thought they were round to accommodate heavier weight sewer workers.

Hey! I resemble that remark!

Here's one. Dodge doesn't make trucks anymore. Everything you see past 2017 isn't a Dodge. It doesn't have the Dodge label either.

Did they ever make a real truck?

Did you ever see a sewer worker shaped like that. Most would fit in the round hole but not yours.

I wouldn't let them anywhere near my holes...

Bondo cures even when it's submerged in lacquer thinner.

You can wax canvas by dissolving wax in Coleman lantern fuel. Stick the cloth in the fuel. Let is soak through. Pull it out and hang it up. After it dries. Waxed canvas. You can use beeswax, white wax, and there's recipes for oiled canvas.

I made a dove pouch for the dead birds. Blood doesn't soak in when the canvas is waxed. Easy to clean.

Don't stand next to a fire or it'll flame up like a big candle. You being the wick.

You do realize, I hope, that the hole's diameter below grade is much larger than the opening? I don't care if the triangle is equilateral or what, I can get that lid to go downhole.

My 1991 Dodge Cummins D250 was a real truck. It really went over 240,000 miles before I sold it and bought a used 2015 Ram 1500 Ecodiesel with 149,000 miles on it. Good trucks.

This guy isn't a truck guy but I still like his approach to looking at vehicles. With that in mind, I guess the answer to your question is "Decide for yourself."

And yeah, mine didn't cost $65K. More like under $20K. I don't like to buy new.

First three digits of your SS number are based on the Zip Code address given at the location and time of the application.

Yep. Mine is "460".
