need to replace channel balance and any other pieces with it for single hung window

Hello! This balance appears to be a match for our Series 770. Check it out and let me know if you agree. The issue is that we don't currently have a 34G stamp for the 34" length; the heaviest stock option for that is the 34E, which only carries 34 pounds maximum.

Now, we should still be able to supply the 34G option for you, but it might have to be a custom order. Before we go any further, can you just verify the exact weight of the sash? According to our records the 34G carries 37 through 40 pounds, which would be too strong.

If your sash is 36 pounds precisely then the 34F may actually be better. This carries 34 through 37 pounds.

Please let me know and we can proceed accordingly.

Gotcha, thanks for confirming. So based on that sash weight I think the 34F is the way to go. 34G would be too strong in my opinion. Have you ever noticed that the sash is too difficult to close in the past? If so, that would be why.

What I'll do now is email you a purchase link and price quote that will let you add 6 of these to your cart, since you said you had 3 windows. This will not include the pivot shoe (which is a match for our 15-129), so don't forget to also add that to your cart before you checkout.

Please let me know if you had any other questions and I would be happy to advise. Or, if you wanted to opt for the 34G stamp to stick with what you had originally, we can do that for you, too. The choice is ultimately yours.
