BendMark Conduit Calculator

BendMark is the conduit-bending calculator that shows its work — and your bender's real numbers. Pick your exact bender (Klein, Greenlee, Ideal, Milwaukee, Gardner Bender and more) and BendMark uses that shoe's true centerline radius, deduct, gain and setback. Or work the classic multiplier method with no bender at all — nothing is ever locked behind a paywall or a pop-up. THE TRUST DIFFERENCE: every result carries a badge telling you which math produced it. Tap it to switch between Exact mode (your shoe's radius) and Field-chart mode (the rounded numbers on your bender card) — so BendMark matches your coworker's chart when you want it to, and beats it for accuracy when it counts. Bends included: - Offset, Rolling Offset, Parallel Offset (uniform or mixed sizes) - Three- and Four-Point Saddles (with the spacing convention shown, not hidden) - Kick with 90° — plus Matching offsets and kicks for parallel runs - 90° stub-ups, Back-to-back, Segmented and Compound 90s - Multiple Bends: lay out a whole run with cumulative marks and one total shrink - Concentric bends and Pre-Cut lengths - QuickCenter multi-angle center marks - Step-by-step bending instructions in your bender's own mark language (arrow, star, rim notch, teardrop) - Bender Specs you can view and fine-tune per shoe — or add a custom bender - NEC 360° rule check on every run Built on published manufacturer catalog data and standard trade math, with every value fraction-native — never a bare decimal on your tape. Works fully offline. One-time purchase, everything included.
