    Hi all

    After scouring the Internet I wonder if anyone could help. I’m intrigued about the number system record vices come in, and was wondering if anyone could shed some light on what it all means.

    1/ the vices concerned come in 52, 52 1/2, 53, 53 1/2 – what does this number system mean, does it mean a bigger jaw width or opening size
    2/ after the numbering, there is sometimes letters – A, D, E and P etc. I’ve come to the conclusion that D is for Dog, i.e it has the build in dog hole, but what about the A, E and P? There are also sometimes combination of letters.

    Anyone any ideas ?????


    I’m not much help with this one bud. Like you I could not find much info. I’m sure someone will help though. The bigger the jaw the further it will open, I think that is correct. πŸ™‚

    Record 52…..7″ jaws
    Record 52 1/2……9″ jaws
    Record 53……10″ jaws

    Thanks for the reply

    yes it seems this is a mystery subject. The jaw size makes sense though, another piece to the puzzle πŸ™‚

    anyone else got any info on what the letters mean?


    E is a quick release
    ED is quick release with dog

    Thanks a lot, very helpful, always wondered what the ‘e’meant πŸ™‚

    Now just need to find out A & P?



    Opposite to quick release I guess.
    A = Arm strength
    p = Patience

    Both of which I have to find and use lol.. Couldn’t resist

    Thanks on the sizes I never really knew either. πŸ˜‰
