Searching for MPCL10

Hi, have you ever seen a casement window keeper like these? There are 3 on every one of our windows. The problem is that the top of some of windows don't get pulled tight enough when latching, leaving a small gap at the top. We think the keepers are worn, as they are just plastic. Each one has an identifier of "MPCL10" on them. Can you help?

Thanks for writing in. I've never seen a keeper like this. I'm forwarding this discussion to one of my senior colleagues who specializes in casement window hardware, and we'll get back to you as soon as we can with more information. Many thanks.

I'm afraid that I'm not familiar with this part. It looks similar to our Silverline 39-552 keeper, but obviously still very different. Could you show us a photo of the lock that interacts with it? That context may help us find a good match.
