NFM doesn't sell Tubes to anyone AFAIK.
You can also use the new Duraflex buckles that were designed for Lindnerhof in the first place.
However the ROC buckles are better noted by users when compared to Tubes.

The Foliage and Tan shades from ITW changed quite a bit a few years back - your buckles are probably the old shade.

3,5mm as standard and 5mm for sewing folded edges on fabric with a tolerable shortening of the finished length.

No news yet. I guess the lawfare phase is ongoing.

So far there appears to be secondhand accounts, hearsay, conjecture, and speculation.

"Just the facts, ma'am."

Emails from Directors of International Sales for both companies are direct sources. I left out some aspects for the sake of discretion.

Hello,

I received a message from my contact at FirstSpear about the 2M ROC buckles we use along with some other brands in Europe and the USA.
FirstSpear believes the buckles infringe on their Tubes pattern and are starting the legal action.

For context: NFM has the distribution rights for Tubes in Europe but FirstSpear acknowledges that NFM is not selling them to anyone.
FirstSpear will not OEM produce carriers for export to Europe because of the NFM agreement so this way is blocked as well.
I heard that the Lindnerhof proprietary buckles might be available for sale.
I would rather use buckles from a manufacturer instead of a competitor for obvious reasons.

I haven't read the Tubes patent and can't judge whether the infringement claim stands (not a lawyer).

I have written about this to 2M and will keep you posted.

Buy a big pad (Olfa 24"x36" for us) and fix a stop on the glass along one vertical edge aligned with the 0" line so you can push the webbing to a fixed starting position without checking.
