Which colors for 27lb , 29" len and 16lb 23" len

A home owner from Cypress TX says:
I have two windows needing sash balance replacements. They most closely resemble the Series 306. Images attached.

One set is 29" long, 3/8" diameter, and has a sash weight of 27lbs.

The second set is 23" long, 3/8" diameter, and has a sash weight of 16 lbs.

These windows are 16 years old, builder standard Champion Style 25, and if there were tips, they are discolored but may have been orange in color.

So I need a pair of 306-29 and a pair of 306-23; can you advise what color tips to order?

Thanks for your help.

Suggest might just be easier to post the weight ranges of each of the available colors.

I agree that the Series 306 is the right base Series, but your shoe is more like our 15-073, which has to be specially attached. It will have to be custom made. I have started two forms for you. All you need to do is fill out the blank fields and submit them each, and then one of our representatives will get back to you with the next step.
