I'm a few weeks away from buying a new single-wide garage door, manually
operated. Stopped into a showroom yesterday when I didn't really have enough
time to talk for long with the guy. He pointed out a type of spring system
I'd never seen: A coil wound around a shaft, with the whole assembly
installed along the wall above the door opening. He said "Somewhat more even
lift compared to the springs you're accustomed to, but probably not worth
the $28 difference unless you're getting an electric opener...". Then his
phone rang, and one of his installers walked in with a clipboard and a
question. It was 10 minutes before closing time, and I decided to stop back
earlier next time.
Any thoughts on this type of spring?
commonly found on bigger doors, the 'torsion spring' system you saw is
actually a higher quality setup than the 'extension springs' you typically
see on single doors. Although, the low price difference he quoted is well
worth it in my opinion. The fact that you are or are not putting an opener
on it is of no value as to the type of spring system.
One caveat is that you have to have a decently high ceiling to use the
torsion springs. My garage door when open is only a couple inches below
the ceiling, so I'm stuck with extension springs. Which reminds me; I
fixed the springs and cables when I moved in but never added the safety
cables - I probably ought to do that. I guess I thought I'd have had
the door completely redone by now, but finances have not permitted. :(

Actually Nate, I just saw a garage with a low ceiling where the
torsion springs were on a bar mounted at the back of the rails,
instead of the front, pretty much even (height-wise) with the top of
the rails. Really cool, but I have never seen this type of thing on
display at a garage door place.
One thing is for sure: My double-wide door is incredibly HEAVY with
only one intact torsion spring. I couldn't get the door open by myself.
The last time a spring broke it was suggested that I replace the garage
door as the original (spec home) door is extremely heavy and is
deteriorating. (It must have a high percentage of particle board as
some of it is visible and rotting away at the (often moist) bottom.
The bid says "insulated steel w/raised panels". Can I expect that door
to be lighter than the one it is replacing?
Yes, and quite durable from what I've experienced. Properly installed with
the correct springs, any door should be easy to lift. Ask the installers to
show you what should be lubricated every year also.
Go look at the door somewhere. They're talking I think about one
layer of steel on the outside with insulation of some sort on the
inside. Or is it steel on both sides, with insulation in the
middle? It would make a big difference to some wrt appearance.
Either spring system should work the same on the door opener or not. If you
are installing the system yourself you may not want the torsion system. One
slip while tightning the springs and you could be hit by the tightning bars
and be hirt very bad. If being installed for you , then no problem.
I disagree. When they break, they remain coiled (loosely) around their
axle. It's a rather safe breakage, actually. Quite loud and certainly
disappointing, but safe.
I do, however, agree with the OP that they can be quite dangerous if DIY
and tightening them. When the door is closed they are under tremendous
tension. Even when the door is open, they are still under enough
tension that, if using an adjustment tool improperly, one can be
seriously injured or killed.
ya, and if you don't know how to drive (about 75% of the GP) then thats
dangerous also. the torsion springs are no more dangerous than crossing the
street after you learn how to do them. And anyone wanting to mess with them
would surely learn first.
They can shatter and fling shrapnel. Less risk if the door is raised,
but if it's lowered and the spring is under maximum tension. (Maybe
they put them in a solid cage these days though, I don't know.)
I think they're most often "adjusted" while already under tension, and
that can be hazardous while not offering the inexperienced a very good
picture of the hazard, which I think is the basis of their reputation
for dangerousness. (Please don't ask how I know.)
The Wayne-Dalton torsion spring system (it probably has a name, but I
don't recall it) in conjunction with their iDrive opener makes for a
remarkably compact spring/opener combination.
We already had "generic" torsion springs and replaced the original
opener by the "generic" iDrive opener. There were initial problems, and
they sent a new controller board under warranty. Since then, I
understand, the unit has been redesigned.
