SZX is a side operator for sectional doors. The hollow drive shaft, to suit the spring shaft, allows a direct drive installation without using any chain transmission system.
The H version features a simpler limit switch board with three cams. Thanks to this feature it can connected directly to the power supply without using any control panel.
The self-braking worm gear makes the SZX/BHS irreversible.
