Do not clamp as indicated (crossed clamp)

Do not grip the package with a clamp truck on the sides indicated.

Who puts it on the box

The sender, when the sides would crush or the contents would be damaged by clamping.

How to read it

Move it another way, for example on a pallet with a forklift if that is not forbidden too.

What it does not promise

It does not promise the package may be clamped on the other sides unless those sides carry the clamp-as-indicated mark.

A mark on a parcel is the sender’s statement about what is inside and how it should be handled. It is not a certificate that the parcel is packed safely, that anyone handled it as marked, or that your carrier accepts it: for what you may send, read the carrier’s own terms.

What it looks like: The clamp picture — a box with an arrow pressing from each side — crossed out.
Standard: ISO 780:2015, symbol No. 7 — Do not clamp as indicated
Kind of mark: A handling symbol from ISO 780, the international standard for handling marks on distribution packages. ISO 780 marks are always black; they say how to handle the package, never that its contents are dangerous.
Also called: No clamp; Do not clamp
