<html> <body> Hi Rob,              Loosen the up stop rail screws, raise the rail fully up. You can then get at the screws.  Hold the damper tray up high with a thick felt mute on top of the dags.  Tighten, then reset the rail. Works for me.

Center pins keep working their way out, or the flanges themselves get broken.. then you gotta take the whole set of dampers off just to get at the tray. Not their brightest moment.
