Single-fin pile Weatherstrip Profile

Pile field includes a continuous barrier fin, typically central or lateral. This page identifies a generic family and the measurements needed to compare sites; it does not identify an exact replacement.

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.
