Can you provide the replacement part number so I can order 4 of these!

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

The measurement is 1 3/32" on the bottom shoe, so I guess it's the 15-004 shoe.

So, the Series 385 in 26" with sash weight 2520?

Cheers,

Norbert

The top shoe looks a little different too. Besides the color, mine is square on the top and the Series 385 looks like it comes with a tapered top.

Don't worry about the top attachment, I think the 19-005 that comes with the Series 385 should work just as well. All it has to do is catch the take-out clip.

Thanks Tom!

I'm going to order enough to replace all the balances on all those single-hung windows!

Cheers,
