Product Overview
The C2G C2G29886 Universal 4K HDMI Adapter Ring with Antimicrobial Technology (Patented US 11,444,419 B2) is a tethered BYOD adapter ring with built-in antimicrobial surface treatment, designed for conference rooms, healthcare facilities, huddle spaces, and classrooms where surface hygiene is a priority. The adapter ring keeps multiple HDMI adapter types tethered together for immediate access by any presenter, while the antimicrobial coating provides an additional layer of surface protection on the ring and adapters.
