Bottom-opening winding system with the GKT telescopic coupling developed by Lock. For ventilation or also as an access point.
Low-cost standard system that is easy to install.
With TFD (double format winding) it is possible to roll up surface areas of approx. 450 m2 with just one EWA power drive. Central roller tube for more stability to wind pressure, less soiling of the sheeting, faster rolling speed and a combination of various types of sheeting and net fabrics possible.
Drive unit can be installed at the end or in the centre of the system, enabling greater lengths, and less torsion on the roller tube.
With HWA manual drive or EWA power drive. EWA conversion is a simple matter.
Drives possible with 3-phase or single-phase power supply.
Fully automatic activation with LSR ventilation controller and wind/rain function.
