29" Series 385 Channel Balance but what weight option?

Question

Hi, I narrowed down my replacement balance to a 29" 385 but the stamp on the old balance is 28 9 C9 Caldwell.  I assume the "28 9" relays the weight but I do not see options that high.  Any suggestions?  Thank you!  -Mike

"28 9" is an older marking that doesn't correspond to ours. Good eye. You need to remove the window sash and weigh it. There's a chart on the S385-29 webpage that will tell you which stamp option to choose based on the weight.
