Multi-Branch Laterals (Manifolds)


How to Order
To order a multi-branch lateral (or manifold), first give the dimensions of A, B, C, D, E, F, G, etc. Then give the branch angle (45°standard) and the radial angles if needed.
Example 1: 12 x 6 x 3 x 4 x 5 x 6 x 7 with 45° branch angles. All branches at radial angle 0°
Example 2: 8 x 6 x 4 x 4 x 4 x 4 with 45° branch angles. Branches C and E at radial angle 0°. Branches D and F at radial angle 180°.
High Pressure Laterals
Efficient and durable high-pressure laterals are essential components for ensuring optimal airflow in commercial and industrial airflow systems. At Spiral Manufacturing Co., Inc., we specialize in delivering high-quality high-pressure laterals designed to meet the unique demands of your projects. As your reliable partner for various above and below ground distribution system components, we offer a comprehensive selection of high-pressure lateral options that enable robust solutions for multiple applications.
Diverse High-Pressure Lateral Options
Spiral Manufacturing offers a wide range of high-pressure laterals, including 45° laterals, tapered reducing laterals, 30° laterals, and saddles. Built with precision, these laterals facilitate seamless airflow and fitment. Our 45° laterals are a standard choice, designed for efficient branching and durable system integration, while our tapered reducing laterals allow for smooth transitions between ducts of varying sizes. The 30° laterals provide an alternative for specialized configurations, and our saddles, available with or without boots, simplify field installation for enhanced convenience.
For added versatility, options like 45° reducing laterals, double parallel laterals, and reducing lateral crosses are available. Our multi-branch lateral manifolds serve complex distribution systems with multiple outlets, delivering consistent performance.
Features for Superior Performance
Each lateral is manufactured with sturdiness and efficiency in mind, enabling optimal airflow distribution. The design flexibility allows customization to any angle, accommodating unique system requirements.
Our high-pressure laterals are built for ease of installation and long-lasting performance. Installation tools and guidance simplify setup, and optional accessories like saddles with boots streamline duct connections. With an unwavering commitment to quality and customization, we aim to exceed your expectations for every project.
