Hi. I am ordering replacement Caradco window cranks (39-155 & 39-156) and saw this neat folding crank handle (39-107FK). My question is: does it cover the "hole" in wood where the crank base is attached? On my window the cut-out hole dimensions are 5" across and 7/8" high. I am attaching photos of window crank area, plus pics of my current Caradco cover w both inside and outside dimensions.
thanks,
Tim

Hi there! The 39-107FK is filly compatible with the operators you purchased. It was designed to work as a substitute for the 39-107 cover, which looks identical to what you have now. I don't think you'll run into any problems.

I have Caradco cranks/covers similar to the ones in this e-mail photo. I want to replace them with the 39-107FK crank/covers. The Caradco crank is centered in the cover. Is the 39-107FK also centered in the cover?

Hello! Yes, the 39-107FK has a centered handle. It's designed to work on operators like the 39-155 and 39-156, which also have centered splines.
