Angle Pile
The ANGLE PILE is a monofilament and/or fiber mixed pile weatherseal. It is a specialized solution for roll screens, bug seals, ventilating seals, and water management, combining monofilament strands and fiber pile for durability and performance. The monofilament locks securely into the metal or fiber screen grid, while the fiber pile holds the screen in place and enhances the insect barrier.
Available in 45°, 60°, and 75° configurations, it ensures versatility and seamless integration into various systems, making it ideal for residential and commercial applications requiring airflow and water movement control.
