Channel Balance

A quick learner says:
The terminal clip broke off of the channel balance and I need to replace it. The channel balance doesn't have an ID number that matches anything on your website. Can you please let me know what type of channel balance I should buy? Thanks.

Thank you for submitting your photos. In order for us to determine an appropriate channel balance, please give us the length of the metal channel and the approximate weight of your sash.
A quick learner says:
The metal channel is 26.5 inches long. With the plastic ends its 28 inches long. The weight is 10.6 oz. Thanks.

I believe you've given us the weight of the balance, and not the window sash. We will need the weight of the window sash. Also, our balances measure every one (1) inch, so you may need to use a 26" balance as a replacement. If the metal portion of your balance is indeed 26 1/2" long, we may recommend using a 27" channel, however it will depend on the balance attachments.

The sash weight is 19.6lbs. Thanks

Our S385-27 balance with 19-005 & 15-004 fittings attached will measure close to 28".

2640 will carry a window sash weight range of 19 through 26 pounds.

The provided weight range is based on 2 balances per sash. Balances are designed assuming friction in the jamb weather-strip will carry a portion of the sash weight. Suggested sash weights are approximate.

Are the terminal clips on these channels universal in size? I want to make sure they fit into the window slits I have. Thanks!
