Casement Window Operator

Question

I have casement windows from the 1980's and need to replace some of the operators. Underneath the crank and cover it says Truth 45034-LH. The length of the arm seems to be about 9 1/2". Also, although the part says LH, it appears it should be RH. Can you help me with getting the correct replacement part?

Thanks for your question. We'd like for you to start with taking a look at both our 39-027E and 39-028E single arm operators. Look over each measurement to see if these are compatible with yours.
