The Concealed Standard
Left & Right Hand
The OA100-BL Centre Spindle conceals the entire operator within the door header and drives the panel through a vertical centre spindle that passes through the door — no surface box, no visible hardware. Handing is set by the hinge side and swing direction; specify left- or right-hand, or pair two units for a synchronized dual-active entrance.
