Removing and adding tension are not the only dangerous parts to the

clamp the door down befor added tension to be safe.



Clamping the door was mentioned in a video posted here. A danger;

besides having the winding bars crack your noggin

Not mention that springs are not only rated by cycles, they are rated
by weight. No reason to assume that because he's getting a better
spring, it's going to be for the wrong weight and cause a catastrophe.
Where do people come up with this stuff?
