Conduit Offset Bend
10° Conduit Offset
Everything for a 10 degree offset: the multiplier, the shrink, a worked example, and the calculator, all from the same math your bender uses.
The 10° Offset Numbers
| Multiplier (field / exact) | 6 / 5.76 |
| Shrink per inch of offset | 1/16″ (0.0625″) |
| 6″ offset: distance between bends | 34.55″ |
| 6″ offset: shrink to subtract | 0.38″ |
Distance between bends = offset depth × 6. Shrink = offset depth × 1/16″. Both bends are 10 degrees, rotated 180° apart.
Calculate Your 10° Offset
Set the angle to 10° and enter your offset depth for the exact mark spacing and shrink.
Frequently Asked Questions
What is the multiplier for a 10 degree offset?
The multiplier for a 10 degree offset is 6 (the exact value is 1/sin(10 degrees) = 5.76). Multiply your offset depth by 6 to get the distance between the two bend marks. For a 6 inch offset that is 6 x 6 = 34.55 inches between marks.
How much does a 10 degree offset shrink?
A 10 degree offset shrinks 1/16 inch for every inch of offset depth. So a 6 inch offset shrinks the run about 0.38 inches, and a 4 inch offset shrinks about 0.25 inches. Subtract the shrink from your measurement so the conduit ends and fittings still land where you need them.
How do you bend a 10 degree offset?
Mark the first bend where the offset should start, then measure 34.55 inches (for a 6 inch offset) toward the free end and mark the second bend. Bend both marks to 10 degrees, keeping the bends in the same plane and rotating the conduit 180 degrees between them so the offset lies flat. Check the depth against your target and subtract the 0.38 inch shrink when you cut or measure the run.
When should I use a 10 degree offset?
A 10 degree offset is a gentle, long offset. Its low angle pulls wire easily and looks clean, and it shrinks little (1/16 inch per inch), but the bends sit far apart (multiplier 6), so it needs room. Use it for shallow steps over conduit or where you want the easiest wire pull.
