NOTE: At present 1/8" and some 3/16" stock have Raychem branding and size printed in a dot-matrix style.
Our stock of 3/16 (some) 1/4, 3/8, 1/2 (some), and 3/4" are in the old stamped ink style.
While there is no PCN for this change, our stock indicates this change was implemented on/around 6/2020, and was predominantly the dot matrix style up until the end of 2023, where we're now seeing more sizes in the stamped ink style again as of 2024.
