Casement windows hinges and operators

Question

Hi.
The first three photos are from a window in my living room. I have Truth 30746 reading on the elbow. I want to change both the hinges and the operator.
The last two photos are from a window in my bedroom. The reading on the base is Truth 30751. I want to do the same - replace hinges and operator.
Thank you for your help.

Hey there!

Thank you for reaching out to us. Take a look at the 39-188 and 39-187 operators, as well as the 36-048 hinge set. Review the specifications for these parts and see how they compare with yours. Note that we recommend replacing the top and bottom hinges at the same time.
