Looking for Roto window cranks

Hi Dan,

Thanks for writing in! There are a few different window cranks that populate when searching for the part information you've provided. To be able to narrow down which of them is the correct replacement, I'll need to see photos of the existing hardware. 

Please feel free to reach out with any questions you might have in the meantime.

Thanks for the photos. The operator you have looks a lot like the 39-329 LH Inverted Split Arm ROTO Operator used along with the 39-323 Roto Folding Crank Handle; the opposite handed operator is the 39-330. 

The link arm appears to be attached to the sash using the 39-553 Roto Sash Bracket; the 39-330 would use the 39-554.

To confirm that these are the right fit for your window, carefully look over the dimensions below.

Hello,

My apologies, I misunderstood the request. To replace your existing hinges, you should be able to use our 36-048 2-Bar Hinge. Although, you'll need to remove the hinge to confirm the exact length of the sill track. You'll also need to confirm the measurements for each of the installation holes; there is a chance they may not be a match so there is a likelihood you'll need to drill new installation hole. If so, we do advise exercising caution so that you do not drill into the glass pane or damage the window frame.

These hinges can be used to replace the left and right hinges; you'll need to replace both the top and bottom hinges to ensure the window continues to open and close properly.
