Window channel balance and t lock pivot shoe

Question

Hello,I've recently replaced the bottom part of my window.I noticed the new window is way more heavier than the old one. A new tempered glass was installed.The existing channel balances were not in a working condition previously.The old window didn't work for a long period of time because I think that the t lock pivot shoes are broken.

Going forward do I buy the same channel balance to replace the old one or I buy new channel balances that fits/pairs with the new weight of the window. The old channel balance is 28C BSI AND ITS 28 Inch long. I'm assuming if I buy new/deferent style channel balances I need to buy a deferent T lock pivot shoe as well. Thank you so much and I'm looking forward for your advice. Have a great day!

Hi there!

Thanks for reaching out to us. We recommend sticking with the original hardware the window was designed to use but you will need a different stamp option since you recently installed new glass. Can you weigh the window sash on a scale and tell us the precise weight? Can you confirm the length of the metal channel as well?

As for the balance, it must be a custom order due to the configuration. Yours uses the 15-170 clip to anchor to the pivot shoe and no stock balance of ours has such a clip. With that said, we'll take the Series 770 and swap out the terminal clip for the 15-170. I'll just need the above information confirmed to get this moving for you.
