Garage door. Then springs will kill you.
^This. Leave this to the professionals. When you’ve seen one let go, it is impressive.
Why are there springs in your garage doors? Over here they are manual rollers or automatic rollers
They balance the door so it takes very little effort/ pressure to open and close the door.
Ah, somehow they do that with the rollers with no spring
You wouldn’t be able to lift the door without the spring acting as a counterweight. It’s usually a big roller just above the doorway on the inside (right near where the track curves in) with cables that run down to the bottom door panel.
So yeah, huge spring under constant tension.
