Hi,

I have several of the same type window, same style balances. Stamped "Caldwell". I have attached pictures and hope you can tell me which parts to order. Are they ordered as singles, or pairs. I hope you can see these pics!
thanks,

Carol

Thanks for posting, Carol. Before we can suggest an applicable replacement non-tilt channel balance, I just need to know a bit more information. First, what is the length of the metal channel? Please do not include the plastic attachments in your measurements.

Next, what is the depth of your shoe? For an example of what I'm talking about, please refer to the chart below and pick out the show that is closest to your bottom shoe. Keep in mind that while a fraction of an inch difference may not seem like much, it is still fairly important for the function of your balance.

Hi Tom, The end does have wings, and the measurement you needed is .98" (15-005?). The length of the metal is 27". Please let me know what else you need to order. Thank you.
