Vinyl replacement window parts

Thanks for writing in! The reason you are having the issue you are describing is because the worm gear in the operator has become stripped. So, when you are trying to turn the handle, that gear is not interacting with the hears on the inside of the operator base. This means you'll need to replace the entire assembly.

To identify the replacement you need, I will need to see a photo of the entire operator. I am especially looking to see a photo of the arm(s) and how the operator attaches to the bottom of the swinging window sash.

Please don't hesitate to reach out with any questions.

Thanks for the requested photo. Your casement operator reminds me of the 39-035 Truth Hardware EntryGard Dyad Window Operator, and its opposite handed version the 39-036. To determine if this is the correct replacement, be sure to carefully review and compare the dimensions below.

I've also tagged the other compatible hardware below.

I believe you may be referring to the glazing bead. To determine if there is a replacement we can recommend, I'll need to see photo of the end profile view of your bead. Take a look at the video below for reference.

Thanks for the photos. I'm sorry to say I was not able to locate a replacement for the glazing bead you have here. It has a very unique shape and the glazing bead we have would not work as a suitable alternative.

Our sincerest apologies we could not be of more help with this repair but please don't hesitate to reach out with any other hardware repair projects you might have.
