    Hi all,

    When replacing an agraffe how is it determined the replacement agraffe will have the same string plane  as the surrounding original agraffes once it is tightened to the plate?

    Thank you.

    I like to lay a short, thin, clear, plastic rule across the adjacent agraffes, on top of the wire so that I can see if the installed one is going to have its holes, (at their top) at the same height.  This is done 1/2 turn away from final so that the new agraffe will actually appear higher than the neighbors by 1/2 the distance from thread to thread before I turn it the last 180º to tighten
