How to measure for compatibility

To ensure a good fit, measure your window track. Look for a track height greater than 0.48 inches (1.2 cm) and a track width less than 0.61 inches (1.55 cm). Depending on track type, you can install on the inside track or the center track.

These guidelines help you assess compatibility while preserving the look and function of your windows. If in doubt, testing a single unit on a discreet area can verify fit before broader use.
