replacing window casement hinges

Hello,

You are correct that the link arm for your old-style ROTO operator is no longer available. That part was discontinued by ROTO and we have not been able to source a suitable replacement for it. With that being said, we can still offer the 39-091 and 39-092 operator bases, along with the 39-224 handle. 

We also do not recommend trying to modify the window to operate as an awning window. Although we do not carry exact replacements for your hinges, we do carry the 36-021HD four-bar hinge and 36-004-10 2-bar hinge. We can't guarantee that with option would work for your application but these would be our best options at this time. We apologize for the inconvenience. 

As we mentioned, unfortunately, the link arm used with the 39-091 and 39-092 was discontinued by Roto and is no longer available. Your best bet would be to see if you could reuse your original link arm with the replacement operator base. 

The hinges and operator are entirely different parts. The hinges connect the top and bottom of the sash to the window frame. The operator is independent of the hinge and is only used to push the sash out and pull it back in. Both parts are important to the overall function of the window but the hinges and operator do not interact with each other.
