Air Duct Mounting Plate

The SPECTRE Air Duct Mounting Plate (SPE-8148) is a precision-engineered component designed to securely fasten 3-inch ID ducting systems in HVAC, ventilation, and tactical equipment applications. This black plastic mounting plate provides a stable, repeatable interface between standard 3-inch ducts and mounting surfaces, making it essential for users who require reliable airflow management in both commercial and specialized environments. Whether you're building a custom ventilation system, integrating air management into equipment setups, or maintaining existing ductwork infrastructure, this mounting plate delivers the structural support and alignment accuracy that professional installations demand.

Constructed from durable black plastic, the Air Duct Mounting Plate features a compact footprint of 3-3/4 inches in length and width with a 1-inch height profile, allowing seamless integration into space-constrained installations. The plate's robust design accommodates a 3-inch inner diameter (ID) duct connection, ensuring a secure fit and vibration dampening during operation. Its lightweight construction—weighing just 0.11 pounds—minimizes installation burden while maintaining structural integrity under normal operating conditions. The mounting surface is engineered to distribute loads evenly, preventing stress concentration and extending the service life of both the duct and connected systems.

This mounting plate is ideal for technicians, system integrators, and equipment builders who need a reliable duct fastening solution for 3-inch ducting systems. Installation is straightforward—the plate bolts directly to equipment frames, wall-mounted brackets, or cabinet structures, providing a standardized connection point for quick duct attachment and removal. Users benefit from consistent dimensional accuracy and repeatability across multiple installations, reducing setup time and ensuring compatibility with standardized 3-inch ID ductwork. For anyone maintaining or constructing ventilation systems requiring secure, repeatable mounting points, the SPECTRE Air Duct Mounting Plate is a professional-grade solution that simplifies assembly and delivers long-term reliability.
