Hopkins 1.75" Soft Action Duplex Spring Assembly
14g spring on 15g spring - 20" long
For use in Cap and Rack blinds and, also, in blinds with long drops as the duplex spring means that it will achieve in excess of the number of turns as a spring twice its length while reducing the torque giving a soft action. Suitable for wider blinds or those with heavier fabric.
These assemblies are the pinnacle of spring design for roller blinds.
