Channel Balance Identification

A contractor from Denver, CO says:

I am looking to replace a dozen window balances. I do not seem to be able to find a match on your web page. It appears to me that they have a 15-005 on one end and possibly a 19-005 on the other.

Stamp: 2720 BSI

It looks like it has a 19-005 top and 15-004 shoe, see our series 385 replacement balance . For the stamp 2720, choose S385-28 with the option 2720.
