Need replacement parts for window slides

Question

The channels are 27" from end to end.  I have 6 of these that I need to replace.  Each one is the same as the other.  The windows are Milguard I believe - see latch on the top in picture.  If i can get the right part, I can install them myself.

Thanks for your post! The window balance you have can be replaced with either the S380-27 or the S385-27. To determine which of these is the correct replacement, you'll need to confirm your shoe's depth.

The 2630 stamp should work for the window but it would be a good idea to double check that your sash weighs between 13 to 19lbs.
