window crank operator

A home owner from studio city says:
Hi I need a window crank operator with a 1/2 inch wide button that is 1/16 thick. The distance from the top of the button to the bottom of the operator is 5/16.

The distance between the screw holes is 3 7/8. The distance from the bottom of the operator to the middle of the screw hole is 3/8. The arm can be 8 or nine inches.

Please let me know if you can help me match these measurements.

Hello Melissa, thank you for contacting us.

Is this operator from a steel casement window? If it is, please take a look at the Swisco 39-001 Casement Operator. You can also browse the other Casement Operators we offer online.

What's the difference between that one and 1962? Yes it's for a steel window. Thanks

I'm sorry, but I am not certain what you mean by "1962"; are you referring to a specific model?
