The Birdie is Beal’s auto-braking belay device and the Orient Express is their specific belay carabiner. It’s got an internal gate to prevent movement and cross loading. A solid all-metal device, the Birdie takes 8.5 to 10.5mm ropes. The shape of the internal cam enables it to lock the rope. The rope exits the front of the device to reduce kinks in the rope. Very smooth lowering action.
