## What is Elbow?

Pick your fittings, get the cut length. Take-outs, weld gaps and thread make-up are subtracted for you, and every number shows its math.

Elbow is a pipe offset calculator for plumbers, pipefitters, steamfitters and sprinkler fitters. Enter the offset, choose the angle and the two fittings, and read the cut from arm's length: "Cut 28-11/16"", with one line under it that says exactly what was taken off.

BUILT FOR FITTINGS
- Offsets at any angle: 11-1/4, 22-1/2, 30, 45, 60 or your own. Solve from offset, travel or run.
- Rolling offsets with the true offset, travel, run and how far to roll the fitting.
- Cut length between two fittings: center to center minus each take-out and the gap at each joint.
- Take-out tables for carbon steel butt weld, forged steel socket weld and threaded, malleable iron threaded, copper sweat, PVC DWV, PVC Sch 40 and Sch 80, ABS DWV, cast iron no-hub and grooved fittings. Every table names the published manufacturer catalog and page it came from.
- Your fittings differ? Edit any take-out. It is marked "edited" everywhere it is used.

SHOW THE MATH
Every result opens step by step: the formula, the numbers put in, and where each take-out came from. Good for apprentices, and for checking before you cut.

CUT SHEETS (Pro)
List every piece of a run, see the total pipe and how many random lengths you need, then share a PDF or print it for the helper. Saved pieces keep the numbers they were made with: if a table is updated later, you see the change and decide.

SLOPE
Slope in inches per foot, percent or degrees, drop over any length, and the low-end invert. Checks the minimum slope for the pipe size from IPC 2021 Table 704.1 or UPC 2021 Section 708.1. Lay the phone on the pipe for a live slope gauge with a flip calibration.

MORE
- Water volume and weight in a pipe, from the real inside diameter of steel, copper, PVC and PEX.
- Pipe size tables: OD, wall, ID and lb/ft for every schedule, always free.
- Equal spread parallel offsets, cut elbows to any angle with outside and inside marks, and 2, 3 and 4 piece miters with a wrap template printed at actual size (Pro).
- Feet, inches and sixteenths everywhere, with a big tape keypad that works with gloves. 1/8" rounding or millimeters if you prefer.
- Works with no signal: in a basement, on a roof, in a mechanical room.

Built for fittings: take-outs, cut lengths, slope. Not a bending app.
