The Model AT frame series is made with seamless aluminum tubing, heliarc welds, shock (stretch) cords and S-Hooks to secure screen edges through grommets. The frame assembles in minutes with factory-provided, slip joint corners. Each system is designed and built to your individual specification and need. Model AT-3 frames are custom engineered to meet your design needs. Its three-inch tube frame construction allows for draping or masking on the jobsite. Factory-applied perimeter masking is available to conceal screen lacing and grommets and give a turn-key finished look. The image width can be curved to a specified radius. When designing a large fixed frame system, please consider the following options: flat or curved screen (frame can be curved to any radius), frame perimeter with or without black masking, wraparound or standard material design (screen fabric can be wrapped around frame perimeter pipe).
