How to install roller blinds

1. First insert the right end of the upper rail into the beaded head, and then insert the left end of the upper rail into the beadless head. 2. Fasten the uncovered rotatable module to ensure that the roller blind will not drop or move easily, and the installation is completed. 3. Gently pull down the bead curtain on the front, and the shutter will automatically rise. 4. Pull down the bead curtain on the back to control the lowering of the roller blind.
