Editorial & correction policy

1. Sources

We only use factual specification parameters from publicly distributed manufacturer catalogs and official interchange documents. We do not access content behind login walls or paywalls, do not copy manufacturer text, images, drawings or logos, and do not mirror other catalog websites.

2. Verification

Dual-path extraction: each catalog is processed independently by two table extractors.
Rule checks cover bore-code arithmetic, weight/load/speed plausibility, unit consistency and cross-reference symmetry.
A record is published only when its confidence score is at least 0.7 and every parameter can be traced to a source catalog version.
A random 5% sample of published records is re-verified every month.

3. Corrections

Reported errors are reviewed within 48 hours; confirmed corrections are recorded with the affected catalog version and shown as a revision note at the top of the page. If a source catalog changes, the affected pages are revised within 48 hours of detection.

4. Trademarks

All brand names, model designations and trademarks are the property of their respective owners. They appear on this site solely to identify compatibility (nominative use), in forms such as “compatible with [brand] [model]”. This site is independent and is not authorized, sponsored or endorsed by any manufacturer. We do not use manufacturer brands in our domain name or site name.

5. Limitation

Specifications are published for reference only. Always verify critical dimensions and ratings against the current manufacturer specification sheet before ordering or installing a component.
