TORSION SPRING ADJUSTER
A torsion spring adjuster for a rolling shutter is provided. A support plate has a first flange with a hole. A wheel is rotatably mountable on the support plate. The wheel has: a drive recess shaped to engage an end of a torsion spring; a first set of recesses around a circumference of the wheel, the first set of recesses being a first lateral distance from a first end of the wheel; a second set of recesses around a circumference of the wheel, the second set of recesses being a second lateral distance from the first end of the wheel. When the wheel is mounted on the support plate the first lateral distance aligns the first set of recesses with the hole of the first flange of the support plate, and the second lateral distance aligns the second set of recess past the first flange of the support plate.
