Skylight operator

A contractor from Cape Elizabeth, Maine says:
Total chain length is little over 12 inches. Should I assume the 9 1/4 " measurement accounts for about 2 3/4" of chain remaining on the teeth of the sprocket of the operator?

I'm not sure if it will match up exactly, but take a look at our 39-379 Skylight operator. See if you can adapt it to your window. It works on the same principle with that "chain" type gearing, but it's different enough that I can't guarantee it will work.
A contractor from Cape Elizabeth, Maine says:
Can I return the 39-379 skylight operator if it won't work with the skylight I'm repairing?
