Snap-in grille with edge safety lock and thick metal wall hooks for strong anchoring, easy installation, and no loosening over time. Large oscillation angle: swings 120°side to side for wide cool air coverage, ideal for any group size. Variable 3-speed air settings give you full control over airflow, keeping your environment cool and comfortable at home or office. Space saving: unlike table, tower, or box fans, this durable fan hangs on the wall year-round, freeing up limited table, counter, and floor space. Durable construction: all-metal build with individually balanced aluminum blades and heavy-duty motor with sealed bearings for long-lasting performance.
