120 mm Fan Standoff Finger Guard
A finger and wire guard for a bare 120 mm axial fan. It bolts on through the standard 105 mm square hole pattern with 4.5 mm holes that take fan screws or M4 bolts, and a 3 mm built-in standoff ring holds the concentric grille clear of the blades. The guard is 120 x 120 x 5 mm. The ring gaps are about 7.5 mm, small enough to keep fingers and loose leads out of a fan you've pulled for a DIY amp, PSU or rack build.
