Square Tubing for HP-75 Card Reader Cards? - Howard Owen - 01-19-2021 03:57 AM
I have quite a few HP75/71B Card reader cards which I want to be able to ship safely. The ideal thing would be the sort of square tubing the cards were distributed with originally. Does anyone know of a source for such tubes, preferably with removable capped ends? Id be interested in an ID of 1.25 cm and a length of 30cm.
Thanks

I Googled square plastic tubes and got quite a number of hits.
I picked one with a sealed end and available endcaps.
