Reinforced drive (DUO)

The reinforced DUO-drive is equipped with a second motor and matching controller. It closes the gap between the record STA 20 all-round sliding door drive, and the record STA 22 unit, which was designed for particularly heavy automatic doors. In contrast to the STA 22 model, however, the DUO drive is also available for drives with low housing covers of 108 and 150 mm in height.
