Hammond DNFG 4.7 in Metal Finger Guard for Muffin Fans

The DNFG is a metal fan finger guard sized for 4.7 in (119 mm) muffin-style tube axial fans. It is intended for IT and AV integrators, OEM engineers, electricians and facilities teams who need to cover an installed fan opening so that fingers and loose items are kept away from the rotating blades while air continues to move freely.

Overall dimensions are 4.70 in (119 mm) high by 4.70 in (119 mm) wide with a thickness of 0.20 in (5 mm), and the circular guard area has a diameter of 4.50 in (114 mm). The guard pattern is designed for optimal airflow, so it can be fitted over a fan without obstructing the ventilation path, and the open wire-style face is easy to clean when dust builds up.

Mounting hardware is included: four panhead self-tapping 10-32 x 1/2 in screws, as shown on the DNFG drawing. That lets the guard be secured over the fan aperture on a cabinet door, panel or rack accessory plate using the same four-corner pattern used by the fan itself.

DNFG is part of Hammond's DNFG Series of metal fan guards, listed under rack accessories and cooling fans, and is used alongside tube axial fans and fan cords. Shipping weight is 0.2 lbs (0.09 kg).

The part is RoHS compliant, REACH compliant, USMCA compliant and TAA compliant, with country of origin Canada, tariff code 7326.90.8688 and ECCN EAR99.
