Channel Balance Inquiry

Question

Hello,

I am trying to identify this window balance and pivot lock shoe. the balance is 1/2 x 9/16.

I will need a lot of these parts so i want to make sure we order the proper stuff.

Thanks for posting. For your pivot shoe, see our 15-129. It looks like a promising match, but you'll want to compare the dimensions with your old part to be absolutely sure.

For your balances, see our Series 770 Channel Balances. Could you confirm the length of the metal channel? This will determine what length you should select. Based on your stamp code this should be 26", but your stamp is a little unusual. Most Series 770 stamp codes start with a number that represents the length of the balance, then show a letter that indicates the spring weight of the balance. Your stamp of '2600' is a little unusual in this regard, and it is not clear what stamp option you ought to select. To know what stamp option to choose, it is best to weigh your window sash. You can then match that precise weight with one of the weight ranges listed for each stamp option on the product page. Let us know what you think.
