I noticed last night that the chain portion of the chain/cable loop on
one of our 15 year old Craftsman garage door openers rattled against the
rail when the door was moving and when the door hit the down limit and
stoppedthe chain was drooping a little bit over the edge of the rail.

I'm assuming this is due to chain wear and/or cable stretch over the years.

There's a threaded tension adjustment where the cable joins the
carriage, but I'm not sure if there's a "right way" to determine how
much to tighten it.

Do I just tweak it tighter until the chain stands proud of the rail at
all times?

Thanks guys,

Jeff
