Genuine Hormann springs assemblies to suit retractable & retractable plus doors (2002 - current) (for single doors).
The spring number (001, 002 or 003) will be engraved on one of the spring end brackets. There are 3 springs in each assembly, and the springs are sold as a single assembly of 3 springs, including end brackets. The springs are not handed left or right.
It is always recommended to replace springs on both sides of the door, so that the door remains balanced.
