How does 26-147 work?

A home owner from USA says:
How does part 26-147 work? I bought a house last year that has several double hung windows. The only way I can "lock" the windows is to slam down the bottom part. A couple of windows no long "catch". What is the proper way to latch the window? Thanks.

Based on what you've described, I don't think the 26-147 is for you. In your case, remove both the and bottom sashes and examine the interlocks between the two. Sometimes one or the other interlock is either bent or dirt has built up to make the two sashes fail to mesh, which in turn causes the locks to not work properly. Also be sure to check your sill for any blockage that could cause the sashes to not mesh.
