Please see our Surplus Dampers that are in stock.

How to order a standard damper:

Just buy the damper in the size want, select your voltage, 24 or 120, then select what side you want your motor mounted, long side or short side (all sizes over 24 inches require bottom “long side” motor mount) and if you want it Normally Open (use when hooking up to a zone control system) or Normally Closed (use when hooking up to a thermostat or switch).

When selecting the motor on the short side of any damper over 24” it is considered Jackshafting.

*Jackshafting requires bolting two dampers together and adding a longer shaft to control all the parts together.

Current cost for Jackshafting is $34.00****Additional Time for production as well

Rectangular Damper Questions You need to answer

to COMPLETE Your Order:

A. Size, like; “08 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 notreturnabledue to size or configuration errors.

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