"I just counted the coils on one of the new pair of 150 pound springs I
installed on one of my 7 foot single width garage doors last week.
There's 145 active turns in it.
Using one turn to make a new loop removes less than 0.7% of the active
turns which is about 3/4" when fully extended, not the 3 or 4 inches you
mentioned, and I won't believe the designers left that little safety
margin there."

For what it's worth: According to the cardboard sleeve on the 100lb,
26", springs I purchased, the maximum extension is 44 inches and the
manufacturer warns against exceeding that extension for safety reasons.
It takes about 42 inches of extension to service a 7 ft. door; that
leaves just two inches of margin.

The original poster has stated several times that it is an extension
spring including saying that it was parallel to the rails.




Then I will apologize now. I did not see those posts. I only saw a couple
of replies.

My normally very dependable news provider has used up all their downtown for
the next 5 years.
