Geometry & Math
In a right triangle, this is the name of the side directly opposite the 90 angle.
What is the Hypotenuse?
This is the term for the "rise" in a section of conduit at a 90 angle.
What is a Stub-up?
This type of saddle usually consists of one 45 center bend and two 22.5 side bends.
What is a 3-Point Saddle?
This is the most common tool used to cut EMT, IMC, and RMC to length.
What is a Hacksaw?
This tool is used for bending RMC and IMC, but should generally not be used for EMT.
What is a Hickey?
This is the distance saved by the arc of a 90 bend
What is Gain?
This is the specific amount of conduit the bender "uses" to make a 90 curve, which must be subtracted from your measurement.
What is Take-up?
A 4-point saddle is actually made up of two of these.
What are Offsets?
This process must be done after every cut to remove sharp burrs from the inside of the conduit.
What is Reaming?
This is the maximum size of conduit typically bent with a hand bender.
What is 1-1/4 inch?
To find the distance between marks for an offset, you multiply the obstruction height by this.
What is the Multiplier (or Cosecant)?
This mark on the bender is used to align the conduit for a back-to-back bend.
What is the Star?
To ensure a 3-point saddle is centered over an obstruction, the center mark must be moved in this direction.
What is "ahead" or toward the obstruction?
When using a pipe cutter on RMC, you should turn the handle this much for every full revolution.
What is one-fourth (1/4) turn?
This is required to field-bend PVC conduit.
What is a Heating Unit (or Hot Box)?
This is the multiplier used for a 30 offset.
What is 2.0?
If you need a 12-inch stub and your take-up is 5 inches, you should place your mark at this many inches from the end of the pipe.
What are 7 inches?
This is the standard shrinkage per inch of depth for a 3-point saddle.
What is 3/16 inch?
Standard conduit dies for threading produce this range of threads per inch.
What is 8 to 18?
These are used inside PVC during heating to keep the conduit from wrinkling or collapsing.
What are Plug Sets?
Calculate the total shrinkage for a 30 offset with a 6-inch rise (using 1/4" shrinkage per inch).
What is 1.5 inches?
This occurs when two bends in the same piece of conduit are not in the same plane (twisted).
What is a Dog-leg?
When making parallel offsets, the conduit length must be adjusted using this trigonometric function.
What is Tangent?
When threading, you should pull the reamer out while doing this to ensure a clean finish.
What is continuing to rotate it?
This is the key to achieving uniform, kink-free bends when using a hand bender.
What is constant foot pressure?
