Hi, I'm hoping you can help me source a replacement for a window crank and guide setup. The aluminum guide measures 13 7/8" long and 11/16" wide at the outside edges with a slot between the roller guides that measures 7/16" wide.
The guide roller piece is secured to the of the mechanism arm and measures 9/16" wide across the center. The bar itself is also 9/16" wide and measures 8 1/2" long from the center of the bend to the end where the roller is attached. The exposed portion of the crank mechanism measures 5 1/4" long and 9/16" wide with 4 holes to attach to the window frame. Only 2 of the 4 holes are used and the distance between the screw hole pairs measure 3 7/8" & 4 3/4"

Hello,
We're happy to help but I can't make out if your operator is mounted from the front of the operator like the 39-045 and 39-138 or from the rear like the 39-477. Look over the operators related on this page to see which one would fit best in your window. Note that these operators are used with the 39-504 channel guide.

Hello,
Thank you for your reply. This is definitely mounted from the front. In looking at the photos, it looks like 39-045 is will work. The finish of my part looks more like dark bronze than the brown option for 39-045.
If I substitute 39-138 so I can choose the dark bronze finish, will the additional 1/2" in the arm length prevent it from functioning properly? Do these come with the crank handles or do those need to be ordered separately?
This issue with the window is that the operator isn't completely closing the window so it almost seems as though a slightly longer arm may allow for greater closing range, but I'm not sure if this logic is correct or not.

Looking at your operator, it does look like the 39-138 could work on your window. Just make sure that the window is wide enough to accommodate the extra 1/2" arm. You will also need to order the 39-114L handle.
As for your window not closing properly, I would suggest trying to manually close your window using your hand with no operator attached. In my experience, this is the best to find out why the window is not closing completely without depending on the operator. If it doesn't close, hopefully, this will help you see what is stopping it.

Thank you for your input on this. I did place the order for the longer arm.
