A free, no-sign-up guide that narrows down a likely replacement window balance from its type, fittings, measurements, and strength stamp.
- For
- People measuring a broken window balance before ordering a replacement
- Worth noticing
- Version 0.1.1 is most specific for common nominal 1/2-inch non-tilt channel balances; other types need further comparison.
Field notes
The finder starts with a guided, eight-step flow; the visible first step emphasizes measuring the exposed metal channel separately from the plastic shoe. It asks users to compare balance type, fittings, shoe depth, channel length, and any strength stamp, while warning that a stamp may indicate spring strength rather than identify the whole part. Version 0.1.1 is most specific for common nominal 1/2-inch non-tilt channel balances; other balance families are recognized but require fuller visual and measurement comparison.
