Happy I bought this one, even though the original part number change was a little confusing...
It was a little confusing at first because the original part number had changed and this part number is the replacement. I was apprehensive to order it but after much research, I took the leap and ordered this one.
It fit my Bostitch SB 2in1 perfect. The original became brittle and broke. This one seems unbreakable and not likely to become brittle so far. It is too early to tell if I would recommend it or not.
Thank you very much.
