Beseler 57MB negative carriers

[dustmite]

Hello,
Does the Beseler 57MB use unique negative carriers, or would they use the same carriers as the 45MX?
Thanks

I use the same carriers as the 45MX in my 57mb, but it has an insert to hold them. It is an aluminum insert.
I made a 5x7 carrier for it out of matboard.
