Atlas IED 51‑4‑HC 4-Inch Economical Steel Baffle with Hyfidrophobic Treatment

The Atlas IED 51‑4‑HC is a cost‑effective steel baffle designed for seamless integration with 4″ speaker enclosures. Treated with Atlas’ proprietary Hyfidrophobic™ nanocoating, this baffle repels moisture by causing liquids to bead and roll off—ideal for high‑humidity, moisture‑prone, or outdoor installations. Featuring sturdy one-piece CRS construction, it minimizes vibration and rattle while offering reliable on-site assembly with included mounting studs.

Finished in clean white, the 51‑4‑HC fits standard (EZ)96‑4 and (EZ)96‑4X mounting rings, delivering a sleek aesthetic and versatile mounting options for a broad range of conferencing, collaboration, and public address systems.
