Riley Z. ★★★★★ Oct 21, 2026

I wasn’t sure if the blades would balance well, but the spider hub is solid and the whole assembly spun smoothly on my first test run. Installation took about 20 minutes using the provided hardware.

Daniel ★★★★★ Oct 20, 2026

The included locking nuts and screws made installation straightforward—everything lined up perfectly with my old hub. My whole house fan is running quieter and more balanced now, which I didn't expect from just a blade swap.

Daniel ★★★★★ Oct 18, 2026

The whole house fan is humming smoothly again thanks to this blade kit—the included spider/hub made aligning everything much less of a headache. The locking nuts held tight on the first spin-up, which was a relief. Exactly what I needed to get that airflow back.
