Need 10 sets of this hardware

Hello! This is a very old style balance that isn't made anymore. The good news is that you can use a modern product like our Series 500 spiral balance, along with a 17-012 bracket (sold separately).

At this stage the two pieces of information you'll need to determine are length and strength. To determine length, measure the height of the visible glass on the sash that's being repaired and add 3" (if it's the bottom sash) or 1" (if it's the top sash).

For strength, all you have to do is weigh your sash on a scale.

Please feel free to reach out if you had any other questions.
