Product Information
This listing retains the supplied FGW-120A / B-5 designation for a 120mm wire finger guard. SUNON’s manufacturer drawing identifies its guard as FG-12 (B-5). The FGW-120A cross-reference has not been independently confirmed, so the dimensions shown here describe the SUNON B-5 / FG-12 reference and should be matched to the supplied item before ordering.
A wire guard fits over a fan opening to help reduce accidental contact with the rotating impeller while leaving an open route for ventilation. It is a passive mechanical accessory: it has no motor or electrical supply and does not replace the fan. The open wire pattern also does not act as a fine dust filter.
Confirm the 105mm mounting-centre spacing, four mounting holes and available clearance against the fan frame and enclosure. Nominal fan size alone is not enough to establish compatibility. Select suitable fasteners for the actual assembly and keep their ends clear of the blades. A fan and mounting screws are not documented as included. Net product weight has not been verified and is therefore left unspecified.
