which way should garage door springs be wound?
1. Wire size. 2. Inside diameter (90% of doors have a 2.0 inside diameter) 3. Spring length (how long each spring is) 4. Spring orientation if ordering just one spring (left wound or right wound). Generally, when looking from within the garage, if the spring is on the left side, it is right wound, and vice versa. It works as opposites, so if the spring is on the right side of the center when looking from inside your garage out to your door, it is left wound.
