Kerf-in bulb Weatherstrip Profile

End-view shows a compressible bulb joined to a narrow insertion stem/base that seats in a cut groove. This page identifies a generic family and the measurements needed to compare sites; it does not identify an exact replacement.

Do not infer: Do not infer kerf width, bulb size, handing, product series or fit from the word 'kerf' alone. No exact product compatibility, OEM identity, material chemistry, generation or supersession is implied.

Measurement workflow

  1. Stabilize the sample without stretching or deliberate compression.
  2. Choose and record the mounting/base datum.
  3. Record the tool and actual resolution before dimensions.
  4. Measure the base/interface before the soft sealing element.
  5. Capture relaxed geometry with minimal pressure.
  6. Measure the receiver separately when accessible.
  7. Record contact motion, insertion/compression direction, sample condition and uncertainty.
  8. Keep compatibility separate: geometry may narrow sites but does not prove fit.

Scope rule: Measurements, generic profile identification and exact replacement fit are kept separate. Use cited sources and your receiver geometry before making a fit decision.
