Single Hung Aluminum Tilt Window Plain Channel Balance Stamped 2940Z, 30 inches long
Trying to identify replacement for damaged channel balances for my windows. Seven windows use plain channel balance marked as 2940Z. The channel is 30 inches long.
The bottom of the "U" (cross-section of the channel) is 0.575 inches wide. The sides are 0.615 inches wide.
Thanks for posting. I'm confident we can replace this balance system for you, but we need a little more information to get started. Can you give us a good picture of the top of the balance, so we can see how it connects to the window track? Can you also give us a good picture of the hook or clip at the bottom that attaches to the pivot shoe? From there, we'll do our best to narrow down what you need. Many thanks.
Thanks for the response. OK, we're getting there. It looks like you have a 30" Series 770 with the 62-105 hook attached. We can custom make this; I just need to figure out what stamp option you need. The one on your balance, 2940, is from a rating system we don't use with these balances. Can you give us the exact weight of your window sash? With that exact weight, we should be able to work out what you need. Thanks.
Thanks. That would put your window sash in the range for the stamp option 30D, which is for a window sash in the weight range of 24 through 29 lbs. I am sending you an email with a custom link to order (14) of these 30" Series 770 balances, stamped 30D, and with the 62-105 hook attached. Let me know if you have any other questions.
