Fair price and great service.

I,ve purchased this model as a replacement for the extisting ones when they fail. There are an exact match and are almost half the price of one from the manufacturer. Along with the user freindly web sight and quick turn around I am very satisfied with there service and would recommend them as a supplyer.

Q: I didn't see mention of it, but are these NEW and not rebuilt? I also assume they are post 2001 vintage that had failure problems (the same failure as the ones we hope to replace).

The ones I bought are new and I haven't had any problems with them in 4 months

Well, it's a fire damper actuator, for air distribution ducts. I've never seen them offered as "rebuilt", but should have a mfg. date code on the bar code label, as I recall. RkyMtnRon, Denver, CO
