We have a 2006 Carver 36MY. Our aft cabin door and aft cabin head door are both "out of plumb" with the door frame. I assume the top rollers are adjustable, and the side closest to the latch is to be adjusted for striker height, followed by the opposite side for door way frame match (aka plumb) So my question is: how in the heck do you get to the top of door adjusting threaded shafts while its hanging inside the roller track? I'd really love a picture of someone adjusting these? As always, your feedback is much appreciated.
