The system can be combined with: Slalom 430 - Arco 470 - Arco 470/2 - Arco 490 - Multiplo 412 - Rotary 444/2 - Rotary 444/3 - Basic 414. For use with curtains 300 cm W and 320 cm H, max. weight 8 kg. Lift 939 uses a chain operated clutch mechanism to lower and/or raise the curtain for washing, without the need to use step-ladders. Thanks to constant regulation of the lifting belt tension, the operating mechanism allows the system to adhere to the ceiling perfectly. The system can be installed with or without the support section. Ceiling or wall installation - for straight systems only.
