    DM4400 Pull Studs

    Hello

    What type pull stud does the 4400 use ?

    BT30 45,°60°,90° or iso30 type ?

    I did look in the dm4400 manual but it only says pullstuds are supplied by Dyna.

    Re: DM4400 Pull Studs

    It uses a custom knob. I need to confirm a dimension, but I believe the attached drawing is correct (but note the DM4400 in the lower right, so it almost certainly is). However, that is probably only for reference. I have mixed feelings about whether or not you would want to make your own. RTS does sell the knobs, but they are not cheap. Their part, 341-14, is $26.46/ea and are apparently stocked. The price is kind of brutal, but thankfully you don't need a ton of them. If you find them less expensive elsewhere, please post here!
