Rectangular Damper Questions need to answer

 to COMPLETE your Order:


A. Size, like; “8 inches x 24 inches”


B. What side the motor is on using the selected measurements; like “8 inch side”


C. Normally Open or Normally Closed when unpowered:

This means with no power applied, is the damper open?

or closed? Important: When used with a zone control system, you will need to order normally open. When used tied directly to a thermostat or switch, you will want to order normally closed.


D. Rectangular dampers are custom made

 and not returnable due to size or

 configuration errors.

Please carefully review your confirming invoice to ensure correct product for your application.

These are CUSTOM, Made-To-Order dampers

‍ that take approximately 10 business days to make

Note: The DuroZone PMB Dampers currently have a 10 day lead time due to the current aluminum shortage, but we have these sizes in stock and ready to ship.
