No support beams? No problem! The BLE AC180™ is built to deploy in large open spaces without the need for support beams or posts for side guides. Our curtains are adjusted to fit “accordion” to your building’s needs. Send us a message to help with the atrium code requirements and how to design the smoke or fire curtains to your next project!
