Channel Balance Identification
Thanks for contacting SWISCO. I think we can help you replace this balance but I'm going to need a little more information. First, could you provide pictures of any attachments at the other end of the balance? These are important for identifying the kind of balance Series it belongs to. Second, could you weigh your window sash? That precise weight will help identify what your stamp number represents. Thanks.
Can you also see if you have these end caps that are on top of the window, please.
The weight of the window is 36 lbs.
Okay, thanks for the photos and for weighing your window sash! It looks like you need our S390-28 Channel Balance. If your window sash weighs 36 lbs, then the 2765 stamp option should suit your needs. These come pre-assembled with their nylon attachments.
As far as your top sash guide, take a look at the 18-019 and see if it matches your old parts.
We use USPS and FedEx for our shipping.
