# 90° stub-up calculator and take-up chart

To bend a 90° stub to an exact height, subtract the bender's take-up (some makers call it the deduct) from the height you want, mark that distance from the end, line the mark up with the bender's arrow and bend to 90°. Take-up is bender-dependent — use your shoe's number.

Mark = stub height − take-up, measured from the end of the conduit.

## The stub-up formula

Bend mark (from the end) = finished stub height − take-up

## EMT take-up / deduct by size

EMT size| Greenlee Site-Rite (deduct)| Klein Tools (take up)| Gardner Bender (deduct)  
---|---|---|---  
1/2″| 5″ (840A/840F)| 5″| 5″  
3/4″| 6″ (841A/841F)| 6″| 6″  
1″| 8″ (842A/842F)| 8″| 8″  
1-1/4″| 11″ (843A/843F)| —| 12″ (933)  
Typical values, bender-dependent. Sources: Greenlee Site-Rite Use Guide 52034125 specifications table; Klein Tools Conduit Bender & Angle Setter guide take-up table (1/2″–1″ EMT); Gardner Bender B-0040 Table 1. Note the 1-1/4″ difference: 11″ on the Greenlee shoe, 12″ on the Gardner Bender iron shoe.

Take-up is the length the bend "uses" between your mark and the back of the finished 90. It depends on the shoe's radius, which is why two 1-1/4″ benders disagree. If your bender has the number cast into the head, that number wins. If not, bend a test 90 on scrap: mark at a known distance, bend, measure the stub, and the difference is your take-up.

## Worked examples

  * 14″ stub in 1/2″ EMT: 14 − 5 = **9″** from the end.
  * 14″ stub in 3/4″ EMT: 14 − 6 = **8″**.
  * 14″ stub in 1-1/4″ EMT: 14 − 11 = **3″** on a Greenlee 843, or 14 − 12 = **2″** on a Gardner Bender 933.

## Back-to-back 90s

For the second 90 on the same stick, Gardner Bender's guide measures from the back of the first 90 to the back of the second and lines that mark up with the star (or "B") on the shoe rather than the arrow. Your bender's markings decide which symbol to use — check the head.

## Common questions

### What is the take-up for 1/2″ EMT?

5″ on Greenlee, Klein and Gardner Bender hand benders. For a 10″ stub, mark at 5″.

### What is the take-up for 3/4″ EMT?

6″ on all three. A 12″ stub gets its mark at 6″.

### What is the deduct for 1″ EMT?

8″ per Greenlee, Klein and Gardner Bender.

### What is the take-up for 1-1/4″ EMT?

It depends on the bender: Greenlee lists an 11″ deduct for the 843 shoe, Gardner Bender lists 12″ for its 933 iron bender. Use the number on your shoe.

### Is take-up the same as deduct?

Yes — same idea, different makers' words. Greenlee and Gardner Bender say deduct; Klein says take up.
