Admittedly i don't trust the dampers that I use there either that they would keep a big transformer when falling.
But as you already write, they should not be sent through world history.
A strips of rubber can be attached to each part, folded over in a “U” form in several locations.
A strip a rubber need some kind of adhesive and it is not too thick so it is good (?) only if transformer are small and lightweight. IMO
You can do exactly the same with Nano tape that is already double-side adhesive (very strong, but easy to remove), and it is made of a material that is extremely dampening.
If you have never tried it, it is difficult to explain.
I've been using it for years for a lot of applications, and for audio in particular for transformers.
1 or 2 mm thick that you can put one on the other.
I don't know how to think of better and I have no ties with any seller or manufacturer. 😉
Those are as easy to DIY as many things. Things that the related marketing sector wouldn't have you believe. DIY about ten bucks to make compared to Boutique rubber bumpers, one million dollars ;0
I think you’re thinking of a different application of a rubber strip. One that wouldn’t be appropriate to mount a transformer.
This would use separate fasteners on each endpoint of the “U”.
So take the “U”, and rotate it 90 degrees.
Then attach the upper leg to the source of vibration, and then the lower part to the chassis.
The vibration dampers do not allow large shear forces. My 600VA transformers would tear down a cylinder vibration dampers in a fall.
However my devices are in my rack after completion.

I bought this dampers from TME.

A company I used to work for, went through this sticky back foam by the box. It has a million and one uses. It comes in 6" x8" sheets. I never seen any thing like it in consumer market, industry only. The sticky is 3M, and be sure where you stick it.. it stays stuck. Point beings some of that would do the trick. I've used it for these purposes its effective.
I might have to visit a couple ex coworkers. Come to think of it its the only place I found two items.

Find the grade, must have been cut out and punched from large sheets, as in lamination, could be a 2 meter wide roll.
Then can try to obtain it, possibly from a supplier who buys rolls and cuts them up into smaller pieces.
There are others who also make a micro bubble epoxy coated material, when you press it firmly, the bubbles break, the two part epoxy mixes, and starts curing.
3M are one of the most innovative adhesive companies in the world, and yes, most of the sales are in bulk quantities.
No ties to them.

No its ordered that way, I've checked around for it and inquired. It comes in a few set sizes no rolls are offered, mini sheets only with nice contoured corners. The largest are not even much bigger. I'll drop in to visit the guys, I used to set up and maintain converting machines in there. The stuff is used often. You can even stack and shape with a razor blade and it holds firm through multi thousand unit production runs. if I'm lucky one just might fall into a pocket. Kidding, just kidding, I always ask for things like samples.
They had a similar product for sticking to furniture and walking sticks.
I think it was called Bump-On.
As a protector, floor to furniture.
Or stick to floor.

Hi,
Let’s say that I consider this way of asking a question shouting through a colorful megaphone not only a useless form of exhibitionism, but most of all a simple proof of poor respect for your interlocutor (please note that I’m not talking just for me, but for any other possible interlocutor and/or reader).
So if you'll ask me the same question whispering, maybe I’ll even reply to you.
Kindest Regards

Plastic fasteners are used to save money. Do not rely on plastic screws to out perform any kind metal in any way except for saving weight.
Besides I don't see why coupling two wholes together with plastic would transfer any less energy anyway. I see the same objects transferring greater energy with plastic due to there being less strength at the connection point. If it were a solid connection the majority of the energy will still travel through the objects larger mass and surface area. And a very low percentage through the fastener itself.

"Compared to metal, plastic gears are much quieter because the teeth of the latter manage to deform, compensating for any misalignments in the rotation. In addition, they have the ability to absorb vibrations. This is due to the intrinsic nature of technopolymers and plastics in general, which makes possible to dampen noise and therefore reduce the transmission of vibrations".

"Essentially, metal is elastic and transmits vibrations easily while plastic is viscoelastic and does not transmit vibrations nearly as well".

However, an effective trick is to not tighten the bolt too strong over the damping material.
Anyway the plastic bolt would have the additional advantage that you cannot tight it too strong otherwise the nut becomes stripped. 😉
P. S.: Actually a typical bolt used in electronics it’s not plastic, but polyamide (nylon by DuPont, 1930) which is a material in itself relatively "soft".

Nylon is one kind of plastic, like aluminum is one kind of metal.
'Plastic' is a short form of 'thermoplastic', in common use to describe at least seven different material families.
A bolt made of PEEK will be as hard as aluminum, and one made of polypropylene will be the same as a Tupperware / Rubbermaid food container, it the same material, really.
Quite common in chemical plants where even stainless steel will get corroded.

ok, I get your point. Still, a solid bolt of almost any kind will transmit vibration/noise. No doubt, metal will be winner for transmitting vibration, yet decoupling effectively done, looks to be superior.
