Research, not directory listings
Each Fieldbook covers one industrial equipment category: every current product family, the attributes buyers actually filter on, and the exact public source behind every value.
11 products are available. One-time purchase, dated snapshot, open about what the sources did not establish.
Every product below is built the same way, so the evidence is comparable across categories. Counts are the actual counts in the delivered files.

Comparing what manufacturers actually publish, on one comparable basis, before you commit design time. Shortlists, spec reconciliation and basis-of-design support.
Building an initial vendor universe or checking an incumbent's own published claims against the rest of the market.
Feeding a bid or an expansion plan with a dated, source-linked category map rather than a set of open browser tabs.
A like-for-like read of what competing families claim in the same category, with the wording and the source preserved.
Industrial Fieldbook produces narrow, evidence-backed industrial research products for teams that need faster first-pass supplier and market screening.
We are a focused operation, not a large firm. Each product is scoped to one category and delivered as a standalone package with a clear coverage date, a stated inclusion rule and open limitations.
