This is the stamp on the side of our balancer. It's a Milgard single hung montecito style window from about 1998. 31" long. I'm just looking for the proper weight range. The window pane itself is about 28 wide by 32 or so high.

Thanks for posting. Sounds like you have a 30" block & tackle balance with a stamp option of 2940. I would double check your length just to be sure. Make sure to only measure the metal channel. I'm afraid that's all I can tell based on your information, though. Now you just need to pick out the top and bottom fittings in order to determine the Series.
I recommend that you look at our Channel Balance Home Page and follow the steps in order to find the Series that best matches what you have.
