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