Adapters and Reducers
Make every transition seamless. Adapters and reducers step between duct sizes, shapes, and connection types — including rectangular-to-round — while protecting airflow, static pressure, and system balance.
Adapters and reducers let you transition between duct sizes, shapes, and connection types without compromising system performance. Whether you're stepping down trunk-line diameter as branches split off, or transitioning from rectangular to round ductwork, these fittings are engineered to maintain airflow and static pressure targets through the change. They're a small component with an outsized impact on system balancing — the wrong transition can create pressure loss and uneven airflow across the whole system.
Engineered Transitions
Engineered to maintain airflow and static pressure through size and shape transitions.
Balances the Whole System
Supports proper system balancing across trunk lines and branch runs.
Rectangular-to-Round Options
Includes rectangular-to-round transitions for flexible system design.
