SWISCO - The Replacement Hardware Authority

Channel balance length of 20-5/8"

A contractor from AZ says:
I have identified the appropriate channel balance for my milgard windows with the 19-005 top and 15-004 shoe, however my existing channels measure 20-5/8" not 21". Is this 3/8" delta a problem or should I be looking at another channel?

The channel stamp is "B.S.I. 20 4 OV"

Thanks for posting! I don't believe that you have our 15-004 shoe. Yours is a special shoe that is only available through a custom order. I'd be more than happy to set one up for you, but I just need to see one last thing.

There should be a metal clip at the end of the string. Could I see a few pictures of it? I'll need to identify it before we can move on with the custom order.

Thanks for your timely response. Attached are the photo's you requested. Additionally, I have included photo's of the top sash guides which I will need as well. In total, I need 6 channel balances and 6 sash guides.
Thank You

Thank you for posting additional detailed images.
For the top sash guide, we recommend taking a look at SWISCO product code 18-008, this could work as a possible substitute.
As for the needed replacement window balances, I will email you a custom ordering link shortly.

I have the same top, shoe and metal clip as this original poster. My balance says 25 5 BSI. Does that mean that I can't use the parts he mentioned (I was going to order those same parts). I won't spend too much on custom parts, so I'm hoping they work. Also, the balances are way to strong for the window. They should be about a 25 2.

Unfortunately, our S385-21 will not work for you. These balance systems are very specific and very delicate, and you'll need the hardware that was precisely made for your window.

I would be happy to help you get what you need, but since your existing balances are too strong we will need a bit more information. Can you give me the weight of your window sash? That will help us find the appropriate stamp option.

My sash weighs 11 or 12 lbs.

Just thought I would let you all know parts ordered and sent based on your help are working great. Additionally, even though the parts required custom order the price was surprisingly reasonable.
