Trying to replace this balance and pin(s) for the lower sash of a double window. The windows were installed ~2006 when the building was built.
The balance says DB K03 35 REG on it (see photo), but there are literally no other markings on it.
Also, the (pivot) pin that slides into the bottom of the window and connect to the sash is broken (see photo) and needs to be replaced.
Thanks!
