The double double rollup door has two drive shafts that wind up or unwind. The wind attack area is divided into 4 fields, allowing a greater distance between pillars. In both single-span and multi-field systems, it is possible to install displaceable supports.
The double double rollup door is particularly suitable for larger door widths and heights.
Tarpaulins and nets can be combined. Optionally, a radio remote control can be supplied.
Depending on the size of the door, it is driven either with a plug-in drive or with a geared motor.
