I got a broken Channel balance. This part is belong to a window made by FBS. On the part I see no label except number 27-4 ( picture attached ). Could you please let me know the part number for this channel balance and where can I order it. Is there any store in Round Rock or Austin carry it ?

Thanks for posting. Sounds like you have a 28" block & tackle balance with a stamp option of 2740. I'm afraid that's all I can tell based on your information, though. Now you just need to pick out the top and bottom fittings in order to determine the Series.
I recommend that you look at our Channel Balance Home Page and follow the steps in order to find the Series that best matches what you have.
