    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.

      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.
