Fast Track Service: most dampers, including "option 1" on odd sizes, ship within 48 hours.

Steps to ordering: Rectangular Dampers:

1. Size: Choose any size above; odd sizes can be accommodated but add a $10.00 charge and expect a ten day delivery. Standard sizes shown usually ship in 48 hours. All dampers are slightly undersized to slip into an existing duct. Add foam weather stripping to outside of housing to take up any extra space and get a tight fit.

2. Choose Motor Configuration: “Power Open / Spring Close” OR "Power Close / Spring Open": Specify what you want this spring return damper to do when power is removed, either open or close. Tip: If you are hooking this damper to a simple thermostat for direct control, order “Power Open / Spring Close”. If used in a zone control system, order “Power Close / Spring Open”.

3. Which side do you want the motor mounted on? Standard and most common is a side (short side of the damper) mounted motor, but you can also have the motor placed on the long side, or bottom, of damper, at no extra charge.

An example part number might look like 3150 10 x 08M PO, meaning an 10 x 8 damper with the motor on the 8 inch side, in a power open, spring close configuration. We will communicate with you prior to fulfilling your order to ensure you get what you want/need.

4. Choose motor voltage: Our standard dampers are 24 volts AC, which is the standard voltage in the HVAC industry, however 110 volts AC is also available for an additional charge of $11.

5. How to order: Just buy a damper(s) in the above size range you need, then in either or paypal "notes" you will have the opportunity to specify the above size and other information; we will not ship your damper until you tell us the size, and other information. If you order an option that costs more, just buy a damper at the price shown, and ask us in to "send you an invoice" and we will correct the price before you pay. When in doubt, just call us at 972-633-8104 and we will answer any questions you have!

Odd Sizes: Yes we will do odd sizes in one inch increments! With odd size dampers (those sizes not listed below), you have two options:

1.Odd size Damper Option 1: Ships within 48 hours: We add a 1 inch filler strip to the non-motor side of the damper. As an example, if you need a 12 x 13 damper, you get a 12x12 damper with a one inch filler strip attached, making it a 12x13 damper.

2. Odd size Damper Option 2: Ships within 10 days: We actually build the odd size damper, ( like a 12x13 damper, as an example) to your specifications.

Each damper is made to your specifications. Dampers are shipped about 1/8 inch undersized in each dimension to insure they will fit in a standard size rectangular duct.
