The Kramer AD-RING-5 is designed for modern presentation environments where a variety of source devices — laptops, tablets, smartphones and more — must seamlessly connect into standard HDMI infrastructures.

This compact adapter ring mounts onto an HDMI cable and holds multiple common adapter leads (such as Mini-DisplayPort, USB-C, Mini-HDMI) on a durable stainless steel ring, enabling quick “bring your own device” connections without scrambling for individual dongles or scavenging adapters from different users.

In practice this means meeting rooms, conference venues, huddle spaces and shared display installations gain a reliable, maintenance-friendly solution: the adapters stay tethered, kept ready, and secured in the ring. The system improves usability for end-users and reduces technician intervention, making it well suited for B2B installations in corporate, educational or rental-AV settings.
