Oh, duh! I'd forgotten that the one-pieces were the only kind to use
extension springs. They had no tracks, which are required for
sectionals and torsions. His conversion will be highly unlikely.

It's time for a new door if you want torsion springs, Bob.


My garage door is a four-section type with extension springs. So are most of
those in my neighborhood -- except the ones that have converted to power
doors. These are old houses with detached garages.


Yeah, around here there are NO one-piece doors, all 4 or 5 sections.
Split between tension and torsion springs.

So they're on tracks? I guess they'd have to attach the sprung legs
directly to the door, then pivot them around the radius curve of the
track, eh? I've only seen one-piece extension-sprung doors here on
the Left Coast. Ditto back in Arkansas, as a chillun.
