I need to replace to channel balances on a window that is 34" wide and 59" tall. The window that slides up and down is counted in these measurements. Separating the window out it is 34 inches wide and 30 inches tall. The channel balance in the window now has the markings 27 3 on it and 158 - 7B (not sure about the last two - hard to ID.)
Looking at your options the 27" series 385 looks like a match - can you confirm.

Hello, thanks for writing in. I'm afraid I can't identify if the Series 385 is correct without seeing a picture. However, keep in mind that the Series 385 and Series 380 are quite similar. The difference lies in the depth of the shoe. Take a look at the picture below for more detail. I would also recommend that you verify the length of your metal channel. Typically a 2730 stamp would indicate a 28" long channel. When determining this dimension be sure to measure only the metal channel; do not include the plastic fittings at either end.
