Milgard channel balance

A handy person says:
Hello. I have a Milgard channel balance that I need to replace. The stamp option on it has a few other notations in it - see photo, so I'm not sure if it just works out to 2640 or if it's something special. The window is probably 30" x 36", unknown weight. Additionally, the channel height is 26 3/4".. so do I just round up to 27". Other than that, it has the 19-005 top and 15-004 shoe and 1/2" wide. Thanks!

If you have the 19-005 top and 15-004 bottom, then you should consider our Series 385 channel balance. I would double check to make sure the length of the metal channel isn't 27", just in case. Usually a stamp of 26 4 corresponds to our 2640 option but you should weigh your window sash just to be sure that's correct.
