Patriot Window tilt lock

A handy person from Warrington, PA says:
Please help identify the correct replacement parts I need for my window tilt locks. I believe part numbers 26-243 and 26-244 may be the parts. I can see what looks like Pat. # 5.139.291 on the underside. There also is a large C

My windows are 13 years old and these locks are breaking regularly. I have 22 windows and want to replace all of these locks.

Thank you

Those parts are close, but you may also want to consider our 26-263 and 26-264. The tooth is curved like yours. Just make sure the dimensions all match no matter which pair you decide to go with. That's the most important thing.
