Thanks for posting! Before I can offer an applicable replacement for this channel balance, I just need to know a bit more information about the two attachments.

Let's start with the bottom one. Please take a look at our 15-004 and 15-005 channel balance shoes, and note their depths. As you can see, they are 1-3/32" deep and 1" deep, respectively. Which one more closely matches your own bottom attachment?

Now for the top attachment. Please see our 19-002 and 19-005. No dimensions needed here, we just need to know if yours has wings or not.

Finally, can you confirm the length of your metal channel? Based on your stamp, it should be 27", not 28". Let me know!

for bottom attachment: 15-004 has the right size.
for top attachment: 19-005 looks right, mine has wings
the metal part is 27". 28" is the overall length.

Thanks for getting back to us. It sounds like you may want to look at our S385-27 Channel Balance. Does that look about right? You may also want to consider our 2650 option, based on your stamp.
