Profile family · Garage bottom seal
Double T-end with U/bulb body Weatherstrip Profile
Two T-shaped attachment edges feed into parallel retainer channels; flexible middle body forms the floor-contact seal. This page identifies a generic family and the measurements needed to compare sites; it does not identify an exact replacement.

Measure before comparing
| Measurement / observation | What to record | Capture rule |
|---|---|---|
| T-end geometry | measurement notes (supplemental profile observation; do not substitute another Reference dimension) | Measure directly when possible; preserve original value/unit and uncertainty. |
| end-to-end spacing | measurement notes (supplemental profile observation; do not substitute another Reference dimension) | Measure directly when possible; preserve original value/unit and uncertainty. |
| channel count | measurement notes (supplemental profile observation; do not substitute another Reference dimension) | Measure directly when possible; preserve original value/unit and uncertainty. |
| laid-flat width | measurement notes (supplemental profile observation; do not substitute another Reference dimension) | Measure directly when possible; preserve original value/unit and uncertainty. |
| body height | overall profile height | Measure directly when possible; preserve original value/unit and uncertainty. |
Do not infer: Do not infer T-end width, channel spacing, retainer brand or door-model compatibility from 'T-style'. No exact product compatibility, OEM identity, material chemistry, generation or supersession is implied.
Measurement workflow
- Stabilize the sample without stretching or deliberate compression.
- Choose and record the mounting/base datum.
- Record the tool and actual resolution before dimensions.
- Measure the base/interface before the soft sealing element.
- Capture relaxed geometry with minimal pressure.
- Measure the receiver separately when accessible.
- Record contact motion, insertion/compression direction, sample condition and uncertainty.
- Keep compatibility separate: geometry may narrow sites but does not prove fit.
