Marks on the stick. Bend it once. Pick the bender you’re using, type the stub or the rise, and get arrow, star, or notch to the nearest 1/16" — with which way to hook. Works with no signal. No ads. Everyday work is here: 90° stub-ups, back-to-back 90s, offsets, kicks, parallel runs, and matching a rise. When you need them, 3-point saddles, 4-point saddles, rolling offsets, and leftover so you can see what still fits on this stick. Take-up comes from the shoe on the bender. Klein, Greenlee, Ideal, Milwaukee, Gardner Bender — the factory numbers, not a generic chart. If yours doesn’t land like the stamp, clock a test 90 and keep that take-up. On an offset you get spacing and shrink. If you haven’t measured to the obstruction, you pick the first mark yourself. Field card follows the multipliers on the bender. Exact is trig. Switch when you want. Share the marks as a text.
