Hello, as per the attached photos I need to replace 2 of these window channels. hopefully you can assist me in identifying which ones these are. I did look at you website and if i had to take a guess I would say possibly Series 377 but I am not sure.
Thank you for your assistance.

Hello,

I agree that your balance fittings resemble the S377. You'll need to measure the length of your metal channel and locate the stamp code on your balance to choose the corresponding strength options for your replacements. Thanks for posting!

Thank you Casey........the metal lenght is 30" and the code which is stamped is (M-29-3). So I am assuming when I order 2 of these the stamp option would be 2930. Is this correct?

Yes, you would need the S377-30 with 2930 strength options. Just let us know if you need anything else.
