I have a flex arm on which the rollers are worn off and it keeps
coming off the rails in the skylight. I have unsuccessfully tried
to 'superglue' a couple of shirt buttons to the metal rivet holding the
rollers in place, and tried crimping a couple of 1/4 split washers
onto the rivet... (both solutions suggested on the list) but they pop
right off when I raise and lower the skylight.

Do the new flex arm rollers have a groove in them which fits the
rail? Can someone take a digital closeup and send me the basic setup
on e-mail in case I'm making some fundamental mistake?

Thanks,
