This is a difficult process. I really need better communication with the team.

Hello, Unfortunately, our part experts are only able to communicate with customers through this discussion board to ensure that each question is answered in the order that it is received. We can help but it looks like you will need the S770-20 channel balance with the 15-036 hook attached through a custom order. If your balances are stamped with 1940, that indicates that you may need a 20D strength option for your replacements, which will support a window sash between 18-22 lbs. I would recommend confirming that your sash falls within the supported weight range since these balances will not be able to be returned for a refund. From there, we'll be happy to send over an order link and price quote for 6 balances. We've also related the cam pivots that we carry on this page that resemble yours. Take a look and review the dimensions shown on our product pages to determine the correct match. These pivots are often used with the 15-105 pivot shoe, but you would need to compare the specifications below to confirm that they match your part. Thank you!

Thanks for getting back to us. Would you like to go with the 20D stamp option for your 20" long balances, which will support a sash between 18-22 Ibs? Also, please note that there is a maximum order of two of each balance, which means that we would send you an order link for two S770-14 balances with (14D) balances with the 15-036 hook attached. These balances will support a sash weight between 16-19 lbs. We recommend replacing the balances on both sides in all cases to prevent damage to the hardware or the window itself. So it sounds like you will need (6) of the S770-20 (20D) balances and (2) of the S770-14(14D) balances, correct? As for the cam pivots and 15-105 pivot shoes, these parts can be added directly to your cart from our website since they are stock items. Once we are able to send over the order links for your balances, you can purchase the custom balances and stock items in one order. |
