Achieve professional and accurate conduit bends with our Electrical Conduit Bend Deduct Length Calculator. This essential tool helps electricians determine the precise mark needed on EMT, RMC, or PVC conduit to create perfect 90-degree stub bends. Stop wasting material and save time by correctly accounting for the bend deduction (take-up) based on conduit type and size.
Formula:
The formula used to calculate the marking point for a 90-degree bend, accounting for bend deduction (also known as 'take-up'), is:
Mark Length = Desired Stub Length - Bend Deduct Value
- Mark Length: The distance from the end of the conduit to where you place the bender's arrow/star mark for the 90-degree bend.
- Desired Stub Length: The intended length of the vertical leg of the 90-degree bend.
- Bend Deduct Value (Take-up): A specific value (in inches) that varies by conduit type and size, representing the material 'consumed' or 'taken up' by the bend.
