I am needing to replace the balance for a croft window. It measures 28 and 5/8 long exactly. It has a white tip. The diameter of the sleeve is 7/16 or maybe 1/2. It seems to be in between the 3/8 and 5/8 diameter options I see you guys do not sell any lengths except whole inches. What do you guys recommend? Thanks in advance for your time.

Hmmm... Croft windows often use the 3/8" style balance. I would recommend triple checking the diameter, just in case. As for the length, I think you'd be safe rounding up to 29".
