Replacement spring mechanisms are available to repair your existing spring operated roller blinds. The 40mm size refers to the diameter of the roller blind top tube that the spring mechanism fits into. We also sell a 32mm size for smaller roller blinds.
When fitted into your roller tube, the spring mechanism smoothly and quietly returns the blind to its pre-set upper stop point.
We offer 2 types of spring mechanism - standard or with a decelerator.
The standard mechanism is 56.5cm long and operates at a consistent speed.
The mechanism with a decelerator is 64.3cm long and operates at a gradually slower speed as it reaches the pre-set upper stop point, similar to soft closing kitchen cabinets.
