The conduit fill calculator for the world. Every other one speaks a single code and a single language. This one speaks yours.

• Three codes, one app. CEC (Canada) · NEC (USA) · BS 7671 / IEC 60364 — covering NICEIC, NAPIT, DIN VDE, the Gulf and the wider IEC world. Switch in one tap.
• 28 languages. The whole app, not just a menu — in the languages actually spoken on the jobsite.
• Verified against the printed code. Every table checked line-for-line against the official code book. You can point to the page.
• Works with no signal. Mechanical rooms, parkades, the middle of nowhere.

Stop guessing which connector fits the cable in your hand. Every fitting that fits, cross-referenced by part number across most manufacturers.

• Teck and ACWU. Match the cable to the connectors that actually fit it — by size, by type, by brand.
• Most manufacturers, one place. Cross-referenced part numbers so you can order whatever your supplier stocks.
• No favourites. Every fitting that fits is shown. Position is never for sale.
• Offline, like the rest. Built for the same conditions — no signal, gloves on, one hand free.
