Steps to ordering: Rectangular Dampers:
1. Size: Choose any size above.  Call us on odd sizes, or check our other ebay adds in our store "Damperdirect".  When you order, we must know:
Size, side you want motor on, and power open or power close.  Put this information under invoice notes, or paypal notes.
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.
4. Choose motor voltage: Our standard dampers are 24 volts AC, which is the standard voltage in the HVAC industry. This damper will replace  any 24vac  two wire spring return damper in the industry, and most three wire dampers.
5. How to order: Just buy a damper(s) in the above size range you need, then in either ebay 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 eBay to "send you an invoice" and we will correct the price before you pay.  When in doubt, just message us via eBay.
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.
