The Arrow BD01 Passage Ball Knob Exit Device Trim provides dependable exterior door operation for compatible Arrow commercial panic and exit devices.

Designed with Arrow's traditional B-style ball knob and D-style round rose, the BD01 combines durable architectural hardware with a classic commercial appearance.

The 01 Passage Function keeps the exterior knob operational at all times. Turning the knob retracts the latch of the connected exit device, allowing entry without a key or electronic credential.

The Arrow BD01 is a compatible exterior trim option for the Arrow AL500 Series Alarmed Rim Exit Devices, as well as selected Arrow S1150, S1250, ED910, and PEC910 Series exit devices.

When properly installed with an Arrow AL500 alarmed exit device, operating the passage knob retracts the latch and activates the manufacturer's designated alarm passage timing. The exterior knob itself is a mechanical component and does not contain an alarm, electronic controller, or battery.

Manufactured with a wrought metal ball knob and matching round rose, the Arrow BD01 is suitable for commercial replacement and installation applications requiring a passage-function knob.

The trim is available in Bright Brass, Satin Brass, Satin Bronze, Oil Rubbed Bronze, and Satin Chrome finishes to coordinate with existing architectural hardware.

Ideal for commercial offices, warehouses, retail facilities, schools, and institutional maintenance applications, the Arrow BD01 provides a practical solution for exterior operation of compatible Arrow exit devices.

Important: This listing is for the exterior ball knob trim only. The panic exit device, rim latch assembly, alarm electronics, and other door hardware are sold separately.
