I am trying to locate the steel casement crank for a steel window sash. Marking show Fenestra Detroit - not other identifying info on the hardware. The hole placement looks different from other items I have found online. The size also appears to be smaller than similar products.

Hello,

We carry Fenestra operators with 9" arms but they're a somewhat different style compared to yours. Review the specifications of our 39-344 and 39-358 and see how they compare to your assembly. These operators have mounting holes for installation on the sill or the lower rail of the window itself. You most likely have a window track like the 39-504 in which the end bearing of the operator arm rides. Take a look and thanks for posting!
