Welcome to SWISCO! These are S395-28 channel balances. You can tell by the winged top attachment and wingless bottom. Let me know if you need anything else. |

Ah, that can be a problem sometimes. I guess sometimes installers only have a couple balances on hand, so they just put whatever in there. Unfortunately, there's no way to know what stamp option is right without weighing your sash on a scale. That's your only course of action. Fortunately, we have a chart on the S395-28 store page that tells you exactly what you need. All you have to do is weigh your sash and refer to that chart. As for installation instructions, we actually have a video that I think you will find helpful. See the video below. |
