Start with evidence you can observe
For a legacy or unbranded seal, missing packaging is not a reason to guess. Build an identification packet from the installed context, the receiver, the end-view cross-section, measurements, markings, and condition.
Decision workflow
- Location first. Record door, window, sliding/patio door, garage bottom, garage perimeter, floor threshold, or another clearly observed location.
- Receiver/interface second. Determine whether the seal is retained by a kerf/push-in stem, T-slot/carrier, adhesive face, surface fastener, retainer channel, floor mount, or an unknown/special interface.
- Body third. Record bulb/tube, foam-clad body, leaf/flap, pile/brush, tension strip, felt, sweep/brush, or other observable construction without forcing a family.
- Measure. Follow Reference for base/backing width, overall height, pile height, bulb dimensions, kerf stem geometry, channel geometry, projection, orientation and uncertainty as applicable.
- Use terminology cautiously. Legacy names, retailer labels and colloquial terms may narrow the search, but they are not compatibility evidence.
- Stop when evidence stops. If the receiver or critical geometry is unclear, keep the record partial/unverified rather than choosing the nearest-looking replacement.
Minimum capture packet
- end-view cross-section photo or tracing;
- installed-location photo showing contact direction;
- receiver/retainer photo after safe removal if available;
- exact markings, printed codes or molded text;
- measurement tool + resolution;
- critical measurements repeated when practical;
- condition notes: compressed, stretched, torn, hardened, painted over, dirty, or unknown;
- original units preserved alongside normalized values.
Safe outcomes
A successful first pass can end at a generic profile family, a mounting interface, or a not equivalent decision between two sites. It does not need to end at a product purchase.
Stop conditions
Do not claim a current replacement when historical identity is not independently established. Do not infer a brand from color, age, installation location, or silhouette. Do not convert dimensional similarity into Source-backed fit.
