Best stability Open

Due to the floor supports integrated into the side door cases, this roll-up door has a self-supporting design and can be installed as a stand-alone system. Due to its application, it is not intended for wall installation. Securing buttons on the outer edge of the door curtain secure it within the guide rails.

Individual manufacturing options Open

The door dimensions can be configured with widths ranging from 600 to 6,000 mm and heights ranging from 1,000 to 4,500 mm. The flexible door curtain is available in several designs and colours.

High-end safety technology Open

The EFA-SRT® MS USD has an interlocking device in accordance with DIN EN ISO 14120 and thus serves as a single-acting, power-operated, movable guard and as a personnel restraint device. In combination with the machine’s control system, the door guarantees the highest level of safety for people working with plant or machinery in the industrial and commercial sector. A safe limit switch serves as an electric locking mechanism between the door and the machinery or equipment. To ensure protection against reaching into the door mechanism, both the winding shaft and the drive are completely covered with sheet metal profiles.
