Why this site exists
Sourced, not guessed
Every size carries the manual number and page it came from. If we cannot source it, we do not publish it.
One question, one answer
No 3,000-word preamble. The number is in the first line, the table is second, the diagram is third.
Re-checked, not abandoned
Each page shows the month it was last verified. Wrong number on your unit? We correct it publicly.

How a size gets published here
- Read the manufacturer manual. Installation or service documentation only. Never a retailer listing, never a forum post, never an inference.
- Record the source. Document number, page number, and the month it was read. All three appear on the published page.
- Publish only when complete. If any of those three fields is missing, the entry stays out of the site. Full detail in our methodology.
