C2G Retractable Universal 4K HDMI Adapter Ring with USB-C DP

The C2G 29879 is a retractable adapter ring that converts a single HDMI connection into a flexible hub for USB-C, DisplayPort, and Mini DisplayPort sources while preserving full 4K support. It attaches to an existing in-room HDMI cable, so presenters can walk in, choose the adapter that matches a laptop, tablet, or phone, and connect in seconds.

The ring extends up to 4.9 feet, giving enough reach to sit comfortably at a conference table or classroom desk. When the meeting ends, the cable retracts smoothly back into its mount, keeping the tabletop clear and protecting the connectors from damage. Each adapter carries a distinct color band that matches the printed label, so users can spot the right plug without trial and error.

The housing and reel have been cycle-tested more than twenty thousand times, which means the mechanism stands up to daily use in busy huddle rooms, training labs, or shared lecture halls. An integrated pull tab offers a firm grip for quick release, and administrators can add a custom logo insert to match company or campus branding. Everything needed for installation ships in the box, and C2G backs the product with a five-year warranty for added peace of mind.

This adapter ring fits facility managers who want to simplify connection options without stocking multiple loose dongles. It also helps instructors move from one class to the next with minimal setup, and it gives visiting speakers confidence that their device will display properly on the first try.
