Need identify and replace three casement opertators.
and the operator appears to be "Truth."
Hey there! Our 39-013 and 39-014 might be the best possible replacements, however, you'll need to review the measurements to confirm. The body of your operator is not as exposed as it appears ours might be, so I can't guarantee that this would be a good fit.
Unfortunately, we do not carry a replacement operator that is designed to use the same adjoining bar that would operate both sashes simultaneously. We apologize for the inconvenience.
