Conex question

[bluedog225]

I goofed up.

On my 20’ conex, I finished out the walls with 2x4 walls and polyiso insulation. Then I covered it with 3/4 ply.

But, I forgot to mark the location for the tie down dealies and I’d like to attach to them.

I can drill a 3” hole and attach but I need to know exactly where they are.

I suspect they are pretty standard.

Any clever ideas on how to figure this out? I’m not able to find any blueprints or line drawings of a conex with these points illustrated.

Thanks

Mine has a loop in the first insent or the corrugated metal 9.5" to its center fron the inside of thw door frome (rectangular tubing. Then they are 55" apart down the wall or every 5th indent of the corigated metal.

I have a couple 20' containers at home I can check of they are the same tomorrow.

Great. Thanks!

Just use a metal detector.

I have six 20's, all but 1 were the same...First valley from the door end, then INCLUDING that valley, every 6th valley EXCEPT for the most rearward is the 5th valley. Total of 5 per side. Yours in the photo looks like it matches these.

The one conex that's different is wacky. the first one closet the doors is in the 4th valley, then every 5th valley. total of 4 per side

Just use a metal detector.

Or a rare earth magnet. You should be able to 'feel' the pull.

...and avoid 'random metal'.

Drill a hole from the inside to the outside. Then you can use the long drill as the pilot for your hole cutter. My hole cutter set uses 1/4 as the pilot bit.

That ought to be enough info. Just look at the photo and estimate the measurement. If they're where you say they are, that would be enough for the OP to cut his holes.

Exactly. As long as the exterior is exposed, he can get the measurements he needs, the interior 'valleys' are the exterior 'peaks'.

Thanks all. The photo I posted is a random internet image.

I can measure the outside to the 6th valley and find it on the inside. That’s the one I need.

Sorry for the late reply.

So of the three 40' and two 20' containers.

All are as stated:
Door *^^^^*^^^^*^^^^*

BUT one of my 20' (Older) has an empty valley before the tie down loop and the spacing is different. Like this:

Door ^*^^^*^^^^*^^^*


So guess there is no standard but I would go with the better odds
