these are the numbers found on the bottom of the base and on each arm of the casement operator.
I Need to find 5 of this exact replacement set to fix five windows in our home.
Thanks,
Bruce

Hey there. This looks like the 39-253LB and 39-253RB Dual-Arm Operators. Please compare. For a cover and handle, see the 39-375 and 39-376, or the 39-451 and 39-452, depending on the style preferred. For the track slide shoe, see the 39-529. For the stud brackets, see the 39-545 and 39-546. Let me know if you have questions.
