I'm in need of 13 replacement cranks for my florida windows. The house was built in 1968(?). There are no visible markings on the windows.

Hardware is 6" long with screw holes on the left.

Start by looking at our 39-061 Keller operator. This might be what you're looking for. Take special note of the hole positions, arm length and the other dimensions we show to confirm that they match up to yours.
