HI there. The plastic cam in our window lock broke. Our house was built in 1999, and the window hardware says Semco. This piece is the lower part in a tandem casement sash lock. I was wondering about a replacement for it. I was also wondering if we'd need to replace anything else... the top part of the tandem looks like it works just fine.
I think Product Code:
38-144 is the replacement (as the measurements are the same), but I wanted to get your expert advice before I order.
Many thanks!
