Abstract
A plurality of studs mount a doctor blade holder to a doctor back in a fiber web machine for slidable extraction of the doctor blade holder in the cross machine direction. Each stud () has a body () with a cylindrical center segment with a protruding nonround flange () formed as a single piece with the center segment. Opposed flats of the nonround flange of the body () may be engaged by the opposed parallel jaws of a conventional wrench allowing ready attachment of the studs to the doctor blade holder and subsequent installing within the channel of a rail which is mounted to the doctor back. A slide bar may be fixed to the doctor blade holder to extend out of the rail for engagement and extraction of the doctor blade holder.
