Window Spring Balance Part

A handy person from Colorado says:
The part is 27 3/4" in length (just the metal part). Markings include "2730" etched on both of them.

Thanks for writing in! Are you certain that the length of the metal channel isn't 28"?  If so, I'm sorry to say that we would not be able to supply you with a channel balance that has a 27-3/4".

Please double check this dimension to confirm.

Hi Jasmine, You're correct, it is actually 28".
Thanks for the fast reply.

I'm happy to help! Thanks for confirming this information. 

Your balance appears to be the S350-28 assembled with a wingless top guide and a winged bottom shoe. You'll need to select the 2730 stamp option.
