The AT frame series are made with seamless aluminum tubing, heliarc welds, shock (stretch) cord and "S" hooks to secure screen edge through grommets. Frame assembles in minutes with factory slip-joint corners. Each system is designed and built to your individual specification and need. AT3 frames are custom engineered to meet your design needs. Three-inch tube frame construction allows for draping or masking on the job site. Factory perimeter masking is available to conceal screen lacing and grommets and give a turn-key finished look. Curved horizontal axis to your specified radius is also available. When designing a large fixed projection screen system, please consider the following options: Flat or curved screen (frame can be curved to any radius); No perimeter masking or perimeter black frame masking; wrap-around or standard material design (screen fabric can be wrapped around frame perimeter pipe.)
