How to Bend EMT Conduit: 90s, Offsets & Saddles

Bending · Take-up, deduct & marks · Updated 2026-08-07

Every EMT bend comes down to the same three decisions: where you put the mark, which line on the bender you set against it, and how far you pull. Get those three right and the pipe lands where the print says, without a scrap pile of practice pieces.

This guide walks through the four bends that make up most of a day's work - the 90° stub, the back-to-back, the offset, and the 3-point saddle - plus kicks, the 360° rule, and the layout mistakes that ruin otherwise good sticks. Every number you need is in the charts below.

Know your bender before you mark the pipe

A hand bender has four reference points, and each bend type uses a different one. Setting your mark against the wrong line is the most common reason a bend lands an inch off. The take-up (often stamped as the "deduct") is cast into the bender head, along with degree lines for reading the angle as you pull.

• Arrow: the start-of-bend line. Align it with your mark for 90° stubs and for both bends of an offset.
• Star point: the back of a completed 90. Use it for back-to-back bends, which measure to the outside of the bend.
• Teardrop (saddle mark): the center of the bender's radius. Use it for the middle bend of a 3-point saddle.
• Degree lines: cast marks for 10°, 22.5°, 30°, 45°, and 60° so you stop the pull exactly on the angle.

90° stub-ups: subtract the take-up, mark, bend

A 90 does not bend at a point - it sweeps through a radius, and that sweep consumes part of your stub height. Take-up (the deduct) is how much. Subtract it from the stub height you need, square a mark that distance from the end of the pipe, set the arrow on the mark, and bend to vertical.

1. Measure the stub height: Say the print calls for a 12" stub in 3/4" EMT, measured to the top of the finished stub.
2. Subtract the take-up: 12" - 6" = 6". Square a mark 6" from the end of the conduit.
3. Set the arrow and bend: Hook the bender with the arrow on the mark, pipe on the floor, and pull with steady foot pressure on the heel. Go a degree or two past 90 - EMT springs back slightly when you release.
4. Check it: Stand a torpedo level on the stub. Shy of plumb, slip the bender on and nudge it; past plumb, flip the pipe and ease it back.

One more for the muscle memory: an 18" stub in 1/2" EMT is 18" - 5" = 13". Mark at 13" and bend. Benders vary by manufacturer, so the deduct stamped on yours always wins over any chart.

Back-to-back 90s

A back-to-back is a U shape: two 90s facing opposite directions, sized to fit between two walls, struts, or box faces. The first 90 is a normal stub bend. The second is measured to the back of the bend, so it uses the star point instead of the arrow.

1. Bend the first 90: Use the take-up method above.
2. Measure the back-to-back distance: Hook your tape on the back of the finished 90 and mark the exact outside-to-outside distance you need - say 36".
3. Bend the second 90 on the star: Align the mark with the star point and bend the opposite direction. The star indicates the back of the new bend, so no deduct is needed.

Offsets: multiplier times depth, plus shrink

An offset is two equal, opposite bends that jog the pipe over an obstruction and leave it running parallel to its original line. Two numbers control the layout: the multiplier sets the distance between your marks, and the shrink accounts for the run getting shorter as the pipe travels a diagonal. The trigonometry behind both lives in the bending multipliers guide; the working chart is below.

1. Measure depth and distance: You need to jog over a 6" obstruction whose near edge sits 60" from the box you are coming out of. You choose 30° bends.
2. Figure the two numbers: Distance between marks: 6" x 2.0 = 12". Shrink: 6" x 1/4" = 1-1/2".
3. Place the marks: Add the shrink to the measured distance: 60" + 1-1/2" = 61-1/2". The offset must finish rising there, so put the far mark at 61-1/2" and the near mark 12" back toward the box, at 61-1/2" - 12" = 49-1/2".
4. Bend both marks at 30°: Arrow on the first mark, pull to the 30° line. Slide to the second mark without letting the pipe rotate, flip it 180°, and bend back to 30°. Sight down the conduit first - both bends must sit in the same plane or you get a dog leg.

Most electricians default to 30°: the 2.0 multiplier makes the math instant and the pull is gentle. Use 10° for long, shallow jogs where appearance matters, and 45° or 60° when room is tight - steeper angles pull harder and shrink more. For scale: a 5" offset at 45° puts the marks 5" x 1.4 = 7" apart with 5" x 3/8" = 1-7/8" of shrink.

3-point saddles

A 3-point saddle carries the pipe over a small round obstruction - typically another pipe crossing your path - using a 45° center bend flanked by two 22.5° bends the opposite way. The outer bends cancel the center one, so the run exits on its original line.

1. Mark the center: Measure from your last coupling or box to the center of the obstruction. Say the saddle depth - the height of the pipe you are crossing - is 4".
2. Move the center mark for shrink: Saddle shrink is 3/16" per inch of depth: 4" x 3/16" = 3/4". Add it to your measurement and place the center mark at the adjusted distance.
3. Add the outer marks: Standard bender charts place the outer marks 2-1/2" per inch of saddle depth each side of center: 2.5 x 4" = 10" left and right. Verify both saddle numbers against the chart supplied with your bender.
4. Bend center first, then the wings: Teardrop on the center mark, pull to 45°. Flip the pipe, set the arrow on each outer mark, and bend both to 22.5°. Keep all three bends in one plane.

4-point saddles and kicks

For a wide obstruction - a duct or a beam - a 4-point saddle is two equal offsets bent in mirror image, one rising before the obstruction and one dropping after it. Lay out each side with the offset math above and keep all four bends in one plane. A kick is a single shallow bend, usually behind a 90, that angles the stub toward an off-center box; the same multipliers apply to it as well.

The 360° rule: count every degree between pull points

NEC 358.26 caps an EMT run at 360° of total bends - four quarter bends - between pull points. Every bend counts: a 30° offset spends 60°, and a 3-point saddle spends 90° (22.5° + 45° + 22.5°). Go past the limit and the run fails inspection - and the wire pull turns brutal long before that.

A typical run: two 90s (180°) + one 30° offset (60°) + one 3-point saddle (90°) = 330°. Legal, but with only 30° of headroom, there is no room for one more 30° offset. Need more direction changes? Add a pull box or conduit body and the count resets to zero.

Common mistakes that ruin sticks

• Wrong reference line. Arrow for stubs and offsets, star for back-to-backs, teardrop for saddle centers. Mixing them up moves the bend by inches.
• Forgetting shrink. An offset laid out without shrink lands short of the obstruction every time. Add it to the measurement before you place the first mark.
• Dog legs. Two offset bends in different planes make the pipe corkscrew. Sight down the conduit before the second pull, or lay a level across the bender head.
• Trusting the chart over the bender. Take-up varies by manufacturer; the deduct stamped on your bender is the number that counts.
• No spring-back allowance. EMT relaxes a degree or two when you release pressure. Pull slightly past the target angle, then verify with a level.
• Kinking the pipe. Weak foot pressure lets the conduit flatten in the shoe instead of sweeping. Keep firm, steady pressure on the heel through the whole pull.
• Bending before checking the degree count. At 330°, one more 30° offset breaks the 360° limit and forces a pull box you did not plan for.

Technique that makes the numbers work

The math puts the mark in the right place; technique makes the pipe follow it. Bend 1/2" and 3/4" EMT on the floor with your foot on the bender's heel - let body weight do the work, not your arms. For the second bend of an offset, many electricians bend in the air, keeping the head aligned by eye so both bends stay in plane. Pull smoothly; a jerky pull walks the pipe in the shoe. And measure twice, because a layout mistake mid-run costs a stick of pipe and twenty minutes of rework.

Frequently asked questions

What is the take-up (deduct) for bending EMT?

For standard hand benders, take-up is 5 inches for 1/2 inch EMT, 6 inches for 3/4 inch, 8 inches for 1 inch, and 11 inches for 1-1/4 inch. Subtract it from the stub height, mark the pipe there, and bend with the arrow on the mark. Always verify against the deduct stamped on your own bender.

What is the multiplier for a 30 degree offset?

The multiplier for 30 degrees is 2.0, so the distance between marks is twice the offset depth. Shrink is 1/4 inch per inch of depth. A 4 inch deep offset needs marks 8 inches apart and shortens the run by 1 inch.

How many bends can an EMT run have between pull points?

NEC 358.26 allows a maximum of 360 degrees of total bends between pull points, the equivalent of four quarter bends. Offsets and saddles count toward the total, so a 30 degree offset uses 60 degrees and a 3-point saddle uses 90 degrees.

Do I add shrink before or after placing my offset marks?

Add shrink before marking. Measure to the near edge of the obstruction, where the offset must be complete, add the shrink for your depth and angle, and place the far mark at that adjusted distance. The near mark goes multiplier times depth back toward your starting point.
