Aluminum core support

[BillyB]

I understand some of the aluminum core supports have the letter "A" embossed on them.. Is there a difference between the ones that do and the ones that do not? Thanks

no

Humm that's interesting.
I thought all of them had the "A" on them.

RedRegal is correct. Not all of them have the "a" on them. I've had several without the "A"
