The Bard 113-707BX Actuator Arm (boxed) is an OEM mechanical linkage component used with Bard wall-mounted HVAC equipment to transfer motion from an actuator to the associated damper or vent mechanism, helping the unit open and close as designed for proper outside air and exhaust control. If your system is not moving smoothly, is binding, or is not fully opening or closing, replacing a worn or bent actuator arm can restore correct travel and reduce strain on the actuator and related hardware. As a genuine Bard replacement part, 113-707BX is intended to match factory fit and function, but you should confirm compatibility by referencing your unit model and serial number or the applicable Bard parts manual before ordering.
* Orders less than $50 may incure a minimum order fee.
Bard uses suffixes like "BX" to manage parts internally. These do not change the physical form or function of the part.
A part number ending in "BX" simply means it is packaged in a box for shipping, rather than for internal assembly use.
Example: 8406-142BX is physically identical to 8406-142.
