Window channel balance and t lock pivot shoe

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.

Good afternoon Emily,

Thank you for your help with this.

I weighed the sash, and it weighs 43lbs. I can confirm the channel of this is 28".

I will also need (2) of these, to repair one window.

Please let me know if you need any additional information. Thank you!

Thank you very much for confirming those details! I'll go ahead and email you a purchase link for (2) S770-28 balances with the 28H stamp, a rivet in the top hole, and the 15-170 clip attached. You can use this link to place an order on our website. A pair of these balances with the 28H stamp is calibrated for a sash weighing 40 to 43 pounds. This link doesn't include the 19-029 s-clip or the 15-169 pivot shoe so don't forget to add your desired quantity to your cart separately.  

Please note that there is a 5-6 week lead time and there is a chance it may take longer.

I'll be here if you have any questions!
