Dayton 508210 Fan Guard

The Dayton 508210 is a steel fan guard designed for 24 inch tubeaxial fans. It fits models 4TM85 and 3C411 using a 5/8 inch mounting hole diameter. The polyester coated finish provides durability for inlet or outlet positions in home or outdoor ventilation setups. It weighs 5.03 units.

Sustained airflow protection

Under continuous operation the guard maintains open airflow while shielding the fan blades from debris. The steel construction resists deformation from vibration and long-term exposure to moving air. Mounting holes align with a 25 5/8 inch bolt circle for secure attachment during extended use. The 1/4 inch overall length keeps the profile minimal.

Installation constraints

The guard is limited to fans with a 24 inch diameter and the specified bolt circle of 25 5/8 inch. It cannot be used with smaller fans or different mounting patterns without modification. Compatibility is restricted to the 4TM85 and 3C411 models listed. Buyers needing guards for other diameters or bolt patterns must seek alternative products.

Questions about this item

Does the steel guard add noticeable weight or vibration when the 24 in tubeaxial fan runs continuously?

The guard weighs 5.03 units and bolts to a 25 5/8 in bolt circle, so it stays rigid without adding measurable vibration during all-day operation.

What mounting hardware must I already have to attach the 5/8 in mounting holes to my existing fan frame?

You need bolts that match the 5/8 in mounting-hole diameter and the 25 5/8 in bolt-circle diameter of the 24 in tubeaxial fan.

Will this guard fit the older 3C411 and 4TM85 models I still use in the same ventilation line?

Yes — the guard is built for the 24 in tubeaxial frame used by both the 3C411 and 4TM85 fans, so it mounts directly without adapters.
