S351-28 28" Series 351 Channel Balance

I have this window balances stamped 2730 BSI, where can I find 4 sets of them with all the parts (including the Standard Guides) to fix 4 windows I have?

I need to replace this balance but having trouble identifying which is the proper replacement. The only stamping in the balancer is "27C". There is not stamping or labeling on the window sash, or jamb anywhere that can be found.

This part mounts to the top of the actual window and seems to serve as a guide. It's in poor condition but I was unable to find one in your catalog that matches the part. I also need the bottom guide for the same window. Pictures attached. The balance spring has "05/22/04 Unique Balance 27D" printed ... (cont.)

Hello! I have 28" window balance channel that need replacement. The existing one doesn't have part number or any indication of model number. Can you help me figure out the correct part? Thank you.

The number 2710 is stamped on the side. I need 4 balances.

Trying to find the right replacement. The channel is 5/8 but I assume 9/16 is what I need. It is 28" long. You will see stamp on photo is 2790__30 with B.S.I. and OJ on it.

The aluminum channel is 28" long x 9/16" wide, 9/16" deep, spring is roughtly 14" long, w/nylon string connected to a hook on one end and a pully on the other, and has the number 2730 stamped on it. I'm needing 10 sets (20 individual).

I need 16 balances but I'm getting any where with the number that was given to me from a email I sent with pictures. I think I need the 2750 ones but not sure one person at your company says I need the the 850 series so I do not know what is what here.

Can I order these on line if so email me the number so I can go and process the order now thanks. I need the number that you use to match mine thanks

A customer has a window with the balances out. The top attachment on one is broken. The bottom of the other is broken. Your video explains install, but I need parts. Can you identify this model from pics?

Not sure which one to choose. My sash says 27 3 Caldwell IM.
