Milgard Casement Windows with Truth Double Arm Operator

A quick learner from Colorado says:
Attached are measurements. Label faded on operator, but lists as Truth. From available options, thinking 39-032 (and 39-031 for other side) would match but the 39-253RB/LB don't have the longer arm dimensions. Planning to order a couple to test out and then verify all are the same size (various window sizes in house), but expect replacement operators for around 26 casement windows (includes dual and single ones).

Hello there!

Thanks for reaching out to us. Our 39-253LB and 39-253RB operators indeed look like a good match. These are designed to use the 39-529 track slider which is sold separately. 

However, I'm afraid I can't say for sure regarding the 39-031 and 39-032. Photos showing the full view of the operator's arms would allow us to confirm. Please note that we also sell the 39-155 and 39-156 that are similar. The difference is the length of the link arm.
