identify window lock balance

Hello,

The balance assembly shown in your photos resembles the Series 795. Note that ours attaches to the window jamb with a screw tab, which is not visible in your photos. You'll also need to locate the stamp code on your metal channel to choose the corresponding strength option for your replacements. Take a look and let us know if you need anything else. Thank you!
