Will your nesting handles replace our crank handles? If it's not too difficult we will be replacing them ourselves, rather than hiring it done.
Our desire is to switch out our vertical blinds to accordion blinds that can be pushed up from the bottom or pulled down from the top. The crank handles we currently have prevent us from installing new blinds.
Attached are photos. There is no writing indicating brand or part number that I could find. Thanks for your help.
