In the Pulley Chain System, blinds are rolled/unrolled by pulling onto a Ball Chain attached at either one side of the blind. Based on Figure 1, it can be seen that Ball Chain goes into a Control which is then connect to the Aluminum tube and the fabric.
The Pulley Chain system is a simple system that allows users to control their desired height easily.
Ideal maximum dimensions is Max Width: 2.2m/ Max Height 2.5m or Max Area 5m², whichever is smaller.
Any dimension larger than the max dimensions would not have any warranty for the operation of the entire system of the blind.
