Hi, I have attached the picture of my window mechanism. Can you guys tell which one I need? I believe I need the model 39-253LB but wanted to double check before submitting the order.
Thanks!

Hi Simone, thank you for posting,
Your operator resembles either the 39-253LB that uses the 39-529 detachable track slider or the 39-438B operator with a connected guide. Both are compatible with the 39-451 or 39-375 cover and handle depending on style preference.
