Thanks to the specific compensating mechanism of the GKT telescopic coupling, no tension is required on the sheeting and no readjustment is possible.
With a single drive unit, the upper edge is lowered and is bottom-rolled synchronously. This eliminates any possibility of collision and makes the system simple to install.
Top-opening roller system with central tube. Less friction because no corner roller. Also, it is possible to override the main doors.
With a single drive unit, the upper edge can be lowered and synchronously rolled up at the bottom. Zero risk of collision.
Top-opening roller system with a unique roller principle for confined installation spaces and cost savings.
Torque is introduced through contra-rotating cable drums. Proven compensating mechanism with telescopic coupling.
