Looking for casement replacement operator
Thanks for your patience during this busy season. I've never seen that number associated with a dual-arm operator, actually. It seems to be primarily associated with the 39-013 and 39-014, which are single-arm. Can you confirm what you have? Seeing a couple photos of the operator in question may also help.
Yep, that's what it looks like. The short arm is part of the hinge and the operator is a match for our 39-013 and 39-014.
If you do need a hinge, I recommend the 36-048. I don't think your original hinge is even made anymore, but our 36-048 should still work well as a substitute. The video below will go into more detail as to what I mean.
