Why fourteen rows state a reason

The basis column is not arbitrary. It is the manual repair of a known gap.

The closure fit table has a column for the basis of each assertion

It holds 55,902 rows and 55,888 of them leave that column empty. Fourteen record something, and the fishing property set that out and left one question open.

The question was why those fourteen

A basis column used on fourteen rows out of fifty five thousand nine hundred and two looks arbitrary until the fourteen are examined.

All fourteen say the same kind of thing

Twelve read that the supplier states the same neck notation on both, at 43MM. Two read the same at 40MM.

Ten product references appear across those fourteen rows

Four clear PET foamer bottles and two white PP foamer pumps at 43MM, plus a natural PP spice sifter disc at 43MM. And a clear and a white PET foamer bottle with a white PP foamer pump at 40MM.

Every one of the ten carries a millimeter neck notation

Not one uses the dash form. Which is the answer: the basis column is populated exactly where the millimeter notation appears.

And the millimeter notation is exactly where an automatic match fails

This shelf demonstrates it. Ten millimeter closures here, five of their six sizes present in the dash form on the container side, and no recorded fit for any of them.

So the fourteen rows are the cases somebody repaired by hand

Where the notation was the millimeter form, a person looked at it, saw both sides using the same string, recorded the pair and wrote down why.

Which turns a puzzling statistic into a useful one

Fourteen out of 55,902 reads as a column nobody uses. Fourteen rows covering precisely the notation the automatic method cannot handle reads as a column used where it was needed.

And it identifies the remaining work precisely

The millimeter rows on other shelves have not had the same treatment. This shelf has ten of them unmatched, nine being sealing discs whose nominal size is present on the container side.

Nothing here fixes that and nothing here asserts the pairs

The finding is recorded because it is measurable and because it explains both the fourteen rows and the fifteen orphans. Asserting a fit would be inventing a record.

The Davis Pack Supply catalog, measured 19 October 2026. The closure fit table holds 55,902 rows and fourteen of them record a basis for the assertion. Twelve read "supplier states the same neck notation on both: 43MM" and two read the same at 40MM. The ten product references named across those fourteen rows all carry a millimeter neck notation: four clear PET foamer bottles and two white PP foamer pumps at 43MM with a natural PP spice sifter disc at 43MM, and a clear and a white PET foamer bottle with a white PP foamer pump at 40MM. The fishing property sets out the rest of what that table records.

The Davis Pack Supply catalog, measured 19 October 2026. Every container on this shelf that records a neck finish uses the dash notation: 48-400, 53-400, 58-400, 63-400, 70-400, 75-400 and 89-400, plus one reading 38DBJ. No container uses a millimeter notation. Ten closures do: one at 38MM, one at 48MM, one at 53MM, three at 58MM, two at 70MM and two at 89MM. Five of those six millimeter values also appear on this shelf in the dash form. All ten of the millimeter closures are recorded as fitting nothing on this shelf, and nine of the ten are sealing discs. Of the fifteen closures here that fit nothing, ten are those millimeter rows and five record no neck finish at all: a dome lid, a dairy lid, two lip balm tube caps and a deodorant lid.

Written from 16 CFR part 1501 and from the catalog as it stood on 19 October 2026. That part provides the test method for identifying toys and other articles intended for use by children under three that present a choking, aspiration or ingestion hazard because of small parts; it does not govern contact lens cases, cufflink boxes, earplug carriers, hair ties or travel kits, and it does not reach any container on this shelf. Nothing here determines whether any article is intended for use by children under three, performs or reports any test, or offers guidance about child safety. A closure recorded as fitting a container shares a neck notation in the supplier record, which is not a test of fit.
