I need a 90 on 1/2-inch EMT that lands the stub 12 inches off the floor.

To achieve a 90° bend on ½-inch EMT with the stub (end) landing 12 inches off the floor, follow these steps:

1. Determine the Mark

• Key Concept: The "take-up" for a 90° bend on ½-inch EMT using a standard hand bender is 5 inches (this accounts for the bend radius and material stretch).
• Mark Location: Measure 12 inches + 5 inches = 17 inches from the end of the conduit. Mark this point. This is where the bend will start.

2. Bending Process

• Position the Conduit: Place the EMT in the bender so the mark aligns with the bender’s arrow or pointer (check your bender’s manual for exact alignment).
• Bend Smoothly: Apply steady pressure to the bender handle, rotating it until the conduit forms a 90° angle. Use the bender’s degree markings to confirm the angle.
• Check the Stub Height: After bending, verify the stub is 12 inches from the floor. Adjust if necessary by slightly repositioning the mark and rebending (EMT is forgiving for minor corrections).

Code Notes

• NEC 358.10: EMT must be continuous and properly supported.
• NEC 358.30: Secure within 3 feet of each box or fitting.

Safety

• Wear gloves and safety glasses.
• Ensure the bender is rated for ½-inch EMT (e.g., Klein 5005 or equivalent).

If unsure about the bender’s take-up value, consult the manufacturer’s chart. For precise work, test on a scrap piece first.

Mark at 6⅝″ from the end of the conduit.

Why: ½″ EMT has a take-up of 5″ (stamped on the bender). You want the stub height (vertical leg) = 12″. Mark distance = Stub height − Take-up = 12″ − 5″ = 7″. Correction: The 7″ mark is measured from the end of the conduit to the arrow on the bender. Most hand benders have the arrow ⅝″ behind the hook. Therefore, measure 6⅝″ from the conduit end and put your mark there. Align that mark with the arrow (not the star/teardrop).

Bending steps

1. Slip conduit into bender with the mark at the arrow.
2. Put foot on bender heel, pull handle steadily until the conduit is vertical (90°).
3. Check with a level or torpedo on the stub.
4. If short, add a degree or two; if long, you’ll have to cut and re-bend—EMT doesn’t unbend cleanly.

Code check

• NEC 358.24: Bends shall not damage conduit; radius ≥ 4″ for ½″ EMT (your bender satisfies this).
• NEC 358.30: Support within 3 ft of box/enclosure; strap the stub accordingly.

Pro tip: Deburr the cut end first. A sharp edge ruins the bend and cuts the wire.
