I have an old style overhead garage door, which incorporates
two springs on each side to more or less counter-balance the
door as it is opened and closed. Each spring is about 24"
long. I've lived here 27 years, and now and then one would
break, and I would replace it, with a little grunting and
Now, I'm not as strong as I used to be, and I cannot pull
the springs enough to un-hook or re-hook them. I'm
wondering if there is a tool or device used by garage door
specialists to stretch these springs for easier installation

Those are extension springs. I hope to hell you are not adjusting
them with the door down!
Raise the door and put a set of vise-grips on the track to keep it
from falling. Then, you can adjust the springs in the relaxed
position. There should be hardly any tension at all, unless you are
very weak - then I would not even recommend being on the ladder.
You must be thinking of a one-piece door. That is not what the OP
Every extension spring I've seen is attached to the horizontal track
at the front and the back hang at the rear. Incidentally, I just
replaced a wooden door that was 50+ years old that was 12' high and
12' wide with extension springs. I couldn't believe it! No safety
cable either. If one of those were to break there would be 500lbs of
spring velocity that would easily slice through a wall on failure.
I would imagine you could hook the back end of the spring in place and
then use a "come along" between the front spring hook and a spot on the
track frame near the door opening to stretch the spring as required to
be able to hook the moving cable pully onto it.
You ARE doing this with the door fully up, aren't you? By that I mean
pushed up to the point where the moving pullies will move as far back as
they can, and the door held stopped there with a pair of vise grips or a
C-clamp on the track.
I'm a bit suprised, because usually, if the springs are sized right for
the door weight, they'll pretty much have no tension on them when the
door is fully up.
Perhaps you got the wrong strength springs?
With the springs disconnected, weigh the door by lowering it onto a
bathroom scale. If it's heavier than the scale can accomodate, make a
simple lever from a piece of board and a brick to multiply the scale's
range. Then make sure you buy a pair of springs rated for the measured
Having lived here in Red Sox Nation for the past fifty something years I
didn't think about the possibility of it being a one piece door either.
One piece garage doors aren't commonly used here because a couple of
inches of snow drifted against the bottom edge of the door makes them
near impossible to begin opening.
I do remember our home had two one piece garage doors when I was a kid
living in snowless San Francisco. <G>
I'm the original poster. I need to clarify the type of
garage door I have. It is for a double garage, and it is
one large panel, about 6'6" x 18'. It is constructed of 2 x
4s and sheet plywood. On each side of the door there is a
bracket that hinges on hardware that is attached to the wall
next to the door opening.
When the door is closed the springs are stretched. When the
door is opened they contract. In the past when one of the
springs has broken I have held the door open using a 6'
ladder. Then I have released the safety catch, and the
broken spring came off very easily. When I attached the new
spring I had to stretch it perhaps an inch or so for it to
hook, and then I would re-install the safety catch.
I recently repaired the door by replacing some water soaked
crumbling areas with fresh, slightly thicker plywood. This
makes the door a little bit heavier, so that when it is in
the full up/open position it is not quite horizontal as it
was before. What I want to do now is, one side at a time,
is disconnect the two springs, and then move the metal
harness into which they fit, into the next hole. (There are
five adjustment holes provided, and mine is in the middle
one, so I can go two steps in either direction.) Then when
I reconnect the springs they will be stretched a bit more,
and thus pull the door up a bit farther.
The only track involved is part of the automatic garage door
opener, and I don't think it is relevant to my problem.
(But, I could be wrong, and I'm here to learn not argue.)
So, with that additional clarification, what do suggest for
a tool or device to stretch the springs that my 75 year old
muscles can't handle? :-)
Ahhh.. so it is a one-piece.
Ask for some help, do you have a neighbor or someone that could help?
Holding that much spring can bring you off the ladder quickly. There
is no tool I know of designed for that, you may be able to rig a come
along - but that can be dangerous too. Don't be a hero - ask for
I recomend a nephew. Failing that, you need some alternative
way to open and close the door. (Maybe a come-along attached
to the back wall of the garage?)
Close the door part way, and shove sticks (wood shingle, bits
of clapboard, or parts of a pallet) into the coils of the spring.
Open the door all the way, and brace it. Move the springs.
Un-brace-the door, lower it, and take the sticks out.
Put the door up, make sure the springs are slack. Find the cable adjuster
on each side near the top rail and pulley. (looks like a little buckle)
you'll be able to see how they work. Also check the cable system and make
sure there are no binds, kinks etc.. It's all common sense.

And on a door that old, if there aren't any safety cables inside the
springs, strongly consider adding some. Be a damn shame if a spring fails
someday when you are standing beside the car as door is going down, and it
tags you in the head.
I also don't understand the comment that because repairs have added
some weight to the door, it no longer opens fully. I can see that it
won't just open fully on it's own, but surely is should if you just
push it up a bit, then use vise grips or similar to keep it there.
Once it's fully open, a lot less force will be required to move the
spring hooks. But, depending on how much weight the repairs added,
it may be necessary to go to heavier springs.
First thing I'd do though is make sure they have safety cables. What
you're doing is going to result in the springs being under more
tension than before. If one snaps, you want to make sure it doesn't
Last year, I was installing a garage door opener, not even touching
the springs. When I was doing the final adjustment, KAPOW! Luckily
it didn;'t hit me, even though I was only a few feet away. All mine
have safety cables now.

I don't see how repairs to a door would increase the weight enough to make
a difference. If the springs are old and stretched (yes they do stretch)
then they need replaced for safety's sake and they aren't expensive at all.
And don't move the hooks to adjust tension, use the cable adjusters.
