Hi, How do I determine if I should use the Series 380 or S385?

My window sash is about 27 X 34. The old channel balance is 2640. I've ordered replacements from you but they don't work so I'm wondering if the channel balances we replaced were perhaps not the original.

Question 1 - My measurement of the channel is 27" . I don't know how to read the stamp on the channel, which reads " 26-5 1X CMC 7. Should I use my measurement of 27".

There is no actual stamp on the old channel balance but in ink it reads, "26 9 34#" then "DL CALDWELL." That is all it reads. There is no other stamp. The pics of the 351 series look the same but I don't know how to choose a sash weight. The sash is approximately 28 H x 44 w. Does the "34#" indic ... (cont.)

The only markings found are on the metal bar 284 D1. Bar is 29 inches long 9/16 wide. Windows have Jordan marked on the locks and are about 26 yrs old. I think they are Series 390 since I do not see any flanges of plastic sticking out and they seem to be the closest match in the photos. If these ph ... (cont.)

This is for a non-tilt window. The metal portion measures 27" X 9/16". It has the following stamped onto the metal, "26 4 KO CALDWELL". I would guess a Series 351, but don't know how to judge the weight, based on the numbers stamped on the metal. Thanks.

I ordered a few S351 27" Sash balances. I have installed them and the weight seems right. When closing the balance the springs make a loud twang noise. Youtube video http://youtu.be/dq68VzpiqpY Strictly I think I should have ordered the S390, but I don't think that this is the issue as there is a v ... (cont.)

I just want to be sure before I place my order... The metal part of the sash measures 27". The stamping on the side is as shown 26-D-40.
