Submit a spec

Add a missing value, correct a wrong one, or add a size we do not list. Every value needs evidence: a link to the page that states it, a manufacturer spec sheet, or a photo of your own measurement. A moderator checks each submission before it is published. Blank is better than a guess.

Values

Fill in only what your source states for this exact product and size. Leave the rest empty. Numbers are plain numbers in the unit shown: no ranges, no "about", no conversions.

Field	Published now	Your value	How measured (photos only)

Evidence Source type

The trust level shown on the site comes from where the page lives, not from this choice: only the brand's own site counts as Verified.

Link to the page or sheet Quote from the source Photo or PDF

Photos: the caliper on the item, readable. We remove location and camera data before storing it. Up to 8 MB.

Notes Note to the moderator

Every value above was read from the cited source, or measured by me, for this exact product and variant. Nothing is estimated or copied from a similar model.
