Truth window crank

Thanks for writing in. I'm afraid we don't have an exact match for this operator. Two of our existing sets, the 39-035 and 39-036, as well as the 39-381 and 39-382, might work as replacement options, but we by no means can guarantee this, and in any event modification to the sill may be necessary. Sorry we can't be of more help, and many thanks for considering our business.
