The Light Source Mega-Airwall Hanger – 4" (MEM4) Airwall Track Clamp

The 4" Mega-Airwall Hanger (MEM4) from The Light Source is a purpose-built clamp for hanging lighting, drape hardware, or rigging attachments directly from hotel and convention center airwall tracks. It locks into the structural portion of the track (not trim) using an expanding panel design, providing a strong, track-friendly connection for ballroom drape lines, room dividers, signage, speakers, and lightweight rigging needs. It’s a go-to hardware piece for clean installs where floor bases aren’t allowed or where overhead support is required.
