Window Crank Assembly Replacement

Home Owner from Winston Salem
We're looking for a complete replacement of our window crank- with the window track and second hinge. Here are the photos- of our Truth. There's a number on the bottom 40055.

Hello,

Thanks for your post! This window operator reminds me of the 39-027E Ellipse Style Single Arm Operator. To determine if this is the right replacement, be sure to review and compare the dimensions below.

The compatible hardware and accessories can be found tagged below this thread, along with the opposite version of the operator.

The window hinge can likely be replaced with the 36-048 2-Bar Hinge Set. To confirm that this is the right fit, carefully review and compare the dimensions below.

You'll need to be sure to replace both the top and bottom hinge at the same time. These can be used for both right and left handed applications.

Before placing the order- we're wondering is 35-048 2-Bar Hinge set needed to make the Single Arm operator work properly? Or can we use existing hardware with a new Single Arm Operator?

Yes, you can replace the operators without replacing the hinges. They are separate parts. I only recommended them based on the request above but if they are in good, working condition, you shouldn't need to replace them.
