National Hardware 7680 Plain Steel Garage Door Left Wind Torsion Spring, 0.243 Wire Diameter by 1-3/4-Inch Inside Diameter by 32-Inch Length Review

Average Reviews:

(More customer reviews)I asked your employee for advise to install longer springs then original because the original broke twice already. The advise was positive.
But when installing I realized that a longer spring for the same door has a shorter travel. It lifts the door withe the same
tension as the old spring but the spring unwinds before it is fully open and when the door opens further the cable that pulls
the door get lose from the pulley and the door get stuck when you close it back. So the door travel has to be shorter.
So a longer spring has more power to lift the door but has a shorter travel for the same door weight.
