Milgard Window Channel Balancer Replacement

A home owner from Livermore, California says:
I believe your S385-27 device will replace my broken balancer. However as you can see from the attached photos my shoe is 1-1/16" in height while the 15-004 is 1-3/32" or the 15-005 is 1" in height. If the smaller shoes is best then I need the Series 380. Would you have any comments on the best part to purchase? Additionally my channel has a Hemmed Edge. I can not tell if your product has this edge. Does your produce come with a Hemmed edge?

Based on these pictures and your measurements, I suggest our Series 385 channel balance. I'd wager your shoe has simply worn down a little from use. Happens all the time. Our balances do not have a hemmed edge but that won't affect the function of the hardware at all.
