"Keep Upright" freight detectors/ spies

[Benni]

Hi TransportHeads,

I am looking for a small gadget that I have seen stuck on freight boxes that should be transported upright.

These things were about half the size of a postcard, made of plastic and maybe 5mm thick.

They featured a little metal ball which was visible through a "window", this ball could move but

was moving on a "sticky" surface, once the box was tilted during transport the ball stopped at the

"tilted moment" and did not roll back to "neutral" position.

There was a sort of scale in the "window" and you could see how far the box had been tilted.

I even recall one sort of these gadgets that was fixed to an upper corner of the box

and had 3 of these "tilt spies" in 3 axes and levels.

I tried to find this on the net and had no success, anyone in the PH massive know what I am writing about ?
