I would contact the company that made the garage door to see if they
can supply the right spring. I had a friend in that business years ago
who told horror stories about people using the wrong spring, and the
damage it caused. You also have to be careful when you adjust them, as
Had that problem a year ago. Fortunately, we had a professional do the
job. One trip to determine what spring was needed, and another trip to
install it. Only one guy was here to install it. I was here for the
install and it turned out to be a two person job.
I had planned to do it all myself and while watching the professional,
learned my scheme would not have worked. Also, the previous owner had
built around the door opener and I had to cut out a bunch of wood the

My sincere advice would be to get a professional to do the job. Our

Might be able to get one made up. I have a one piece steel garage door
that swings up, with a coil spring on each side to assist. When one

some longer springs. IIRC, it was about $60 for the pair, which wasn't
too shabby. They estimated the door dates from the late 50's to early

No, no, no !! Those guys are out-and-out crooks!! I ordered some
rollers from them & was a little puzzled/surprised when they didn't take
a credit card. Checks only. When they cashed the check & didn't send
the rollers, and didn't answer the phone or email, I started looking
around the web. I found a consumer review site with lots of the same
complaint - non delivery. You probably know how little help my bank was
- unlike credit cards, checks don't have a chargeback mechanism. I was
out $25 & I considered it a cheap-enough lesson.
BTW, there was another online vendor with a similar history, so I went
through Amazon. A little more expensive, but not that much.
