How to Determine if Torsion Spring is Left Hand or Right Hand Wound:
Standard springs are coded red and black. Red is right hand wind. Black is left hand wind. Always determine the wind of the wire.
To determine if you are ordering a right wind spring or left wind spring the easiest way would be check the coloring coding - if is it red or black.
Please note the side of door the spring is mounted DOES NOT indicate spring wind needed. Standard garage door systems have the right hand wound red winding cone on the end and will be mounted w/ the red winding cone pointing towards the LEFT. The left hand wound black winding cone will be mounted w/ the black winding cone pointing towards the RIGHT.
Right hand wind would be wound counter clock wise in this diagram with the spring mounted on the left side of bracket.
Left hand wind would be wound clockwise in the diagram with the spring mounted on the right side of bracket.
After you've determined the the left & right hand winds you should have enough information to order.
