/ SYSTEM ACCESSORIES

SBC-Compliant Components

Every volume damper, fire barrier, and access fitting is stamped for structural compliance. Engineered for rapid on-site assembly to eliminate installation bottlenecks.

Volume Control Dampers

Certified Fire Dampers

Airtight Access Doors

Heavy-duty steel dampers featuring reinforced blades and manual locking quadrants for precise airflow balancing.

SBC-compliant fire barriers equipped with fusible links rated for immediate closure under extreme thermal stress.

Insulated double-wall doors with positive-seal gaskets and heavy cam locks to prevent pressure drop.

Precision Fittings

Our calibrated elbows, reducers, and couplings feature machine-formed gaskets. This guarantees airtight connections and minimizes friction loss throughout high-velocity runs.
