Gasket
Thanks for posting, and Happy Thanksgiving. Do you mean a shim that works with this casement lock? If so, see our 38-036S. Take a look and see if you think this is what you need. Pricing is listed on the item shop page. Let me know if you have further questions.
No, not the shim. Attached pics show a gasket on the old handle I replaced with attached gasket I'd like to replace also
Thank you
Thank you for these photos, they're a huge help. Unfortunately it does verify that we don't sell the kind of gasket you're looking for. That said, you may be able to pick up felt or rubber material at a local hardware store and cut it to the size needed. I've done that myself for hard-to-find gaskets and find that it works well.
I'm sorry that this isn't something we're otherwise able to supply.
