“The Cube” – A Flexible Residential & Light Commercial Mixing Box / Economizer Solution

by | Jan 15, 2026 | Mixing Boxes & Econos

In retrofit and service work, surprises on the jobsite are practically guaranteed. Ductwork that doesn’t match the drawings, last-minute layout changes, or an unexpected configuration can turn a straightforward installation into a time-consuming headache. When time is tight, installers need options—and adaptability becomes essential.

That’s where a reconfigurable mixing box design makes all the difference.

Why “The Cube” Exists
Traditional economizers and mixing boxes are typically ordered with fixed damper orientations. If the ductwork doesn’t match the ordered configuration, you’re forced to:

  • reorder the entire unit
  • wait days or weeks for delivery
  • renegotiate with the customer
  • work around a system that doesn’t line up correctly

“The Cube” concept was developed as a universal, field-adaptable mixing box designed specifically to solve this problem for residential and light commercial installations.

Field-Configurable Flexibility
The Cube is designed as a modular, generic-size mixing box that gives installers the ability to relocate the Outside Air (OA) and Return Air (RA) dampers directly in the field—without cutting, fabricating, or reworking the box.

Reconfiguration is simple:

  1. Remove a panel
  2. Move the damper assembly into the desired opening
  3. Replace the blank-off plate
  4. Reconnect the linkage
  5. Reassemble

This gives technicians the freedom to adapt to unexpected site conditions on the spot and ensures a correct fit regardless of the building’s existing duct layout.

Available Sizes & Airflow Capabilities
“The Cube” is available in three standardized outer dimensions, making it easy to stock, transport, and deploy:
