Thanks for posting! Before I can offer an applicable replacement for your channel balance, can you please confirm that the length of your metal channel is 26"? With your stamp, it should be 27". Please double check and let me know! Make sure not to incorporate the plastic attachments in your measurements.
My mistake. It is 27 inches long and that is just the metal.
Looks like the right one. I'll let you know how they worked when I install them!
