Channel Balances for a Atrium Window

A home owner from Littleton, Colorado says:
One of my channel balances came apart when I took the window out to clean it. I have attached pictures and the metal channel is 28" long 5/8" wide and 5/8' deep.
The numbers on the channel is : 86 27-4 HC5 CMC 87

Hopefully I can order a new one or get this one repaired if I can send it back

Thank You,

Hey, thanks for posting. I've narrowed this down to two possible channel balance Series: either our Series 380 or our Series 385 balances.

Now, as you can see, there is only one difference between these two Series, and that is their bottom shoe. The Series 380 uses the 15-005 while the Series 385 uses the 15-004. I can't quite tell what you have based on your pictures, though. Please carefully compare their dimensions to your own hardware and see which is a better match.
15-004 and 15-005

It would be the 15-005

Is it safe to order the series 380?

If you have the 15-005, then I think our Series 380 is a good choice, yes. Refer to the post I made above for more information on what shoe goes with what Series.
