Casement lock

Thanks for reaching out! There is a possibility we can provide you with a replacement for the Semco lock you are searching for but I'll need to see a photo of it to identify it. Unfortunately, I cannot make a recommendation based on the brand or the part information provided.

Please let me know if you have any questions in the meantime.

Thanks for the photo! Your casement lock looks like it could be the 38-144 Primary Casement Sash Lock; although, you'll need to carefully compare the dimensions and design to confirm. This lock is non-handed, so it can be used for both left and right applications.

The keepers compatible with this lock are the 38-276 and 38-277 Casement Sash Keepers.

I'm glad I could be of help to you! Please don't hesitate to reach out with any other hardware repair projects you might come across.

Have a great weekend!
