Components

The AC-21 door operators transmit the power to the door with the help of a revolving

toothed belt. They are normally fixed to the wall, as the rails cannot take up the

forces resulting from the action of the mechanical brake.

The following picture shows the components of a AC-21 door operator system for

sliding doors.
