Intry Verified receipt

Is the Intry Conduit Bending Calculator accurate?

The provenance receipt for the Intry Conduit Bending Calculator: the exact authority its values derive from, the edition they are keyed to, who has final say, and what our automated checks hold them against, rebuilt from their cited source.

The receipt

Calculated from

Bender-manufacturer offset multiplier table · Bend geometry (trigonometry) · Bender-manufacturer 3-point saddle table · Bender-manufacturer shrink-per-inch table · Hand-bender take-up (EMT) and gain (every type). Reused verbatim from the locked engine, never re-written for this page. The documents it rests on are listed in the source receipt on the tool page.

Edition

NEC 2023 Chapter 9 Table 2 (minimum bend radii), for the feasibility check only; the bend math is geometry and the bender maker's chart

Checked

Before any release, an automated check runs the locked engine that produces these figures and holds its answers against values written from the source it cites, so a checked number answers to its source and not merely to itself. The check covers the cases someone wrote a check for, not every input the tool accepts: it tells you where a number comes from, and it is not a proof of every value. As of the current build that suite holds 30959 checks, and this page has to clear them too. This is our own deterministic gate, not a third-party audit.

Runnable

Exposed at the Intry MCP endpoint. An AI assistant can run this calculator, and before each release an automated check confirms the answer it returns is identical to the one the website's own engine produces.

Final say

Field-verify against the actual bend. Bender take-up varies by tool and shoe.
