A hickey bender is used to bend conduit in small bends with short segments , for instance, in order to bend a 90° bend with this type of bender you would bend 9 each 10° bends with short gaps in between them.
How do you bend conduit with a hickey bender?
Place the “start” end of the conduit against a wall. Slip the hickey over the other end and line it up with the “bend” mark. If the hickey has a mark that reads “0,” line up that mark with the “bend” mark. Pull up on your bender handle until the conduit is vertical.
What do the marks on a conduit bender mean?
Bender Diagram
Arrow: Used to line up offset and outer marks for saddle bend. C. Star: Indicates back of 90° bend, for back to back bends. D. Marks: The degree marks indicating the angle of the pipe bent .
What is a hickey in electrical terms?
A hickey fitting is a simple metal part that allows you to connect the threaded nipples of two different sizes to an electrical box . You use a hickey when installing a chandelier or other type of a hanging light fixture.
How do you measure conduit bends?
Measure from the end of the conduit and make a mark at 7 inches to indicate the start of the bend. Slip the end of the conduit into the bender so the 7-inch mark is aligned with the arrow. This 7 inches, plus the “Stubs 5 to arrow” will give you the total horizontal run of 12 inches, including the bend.
What is the take up for a 90 degree bend in 1/2 EMT?
Since the 90 is the most basic of bend you’ll learn, there’s only a few steps to make sure you’ve done it right. #1 – Measure how long you need the stub up length. For this example we’ll use a stub up length of 8 inches (8′′). Using the table above we know the take up for 1/2 inch EMT is 5 inches .
What is a Chicago bender?
A Chicago bender is a manual mechanical conduit bender that gets it’s name from...well... I don’t know. It’s just trade slang for this type of bender. These types of benders are primarily used for RMC (rigid metal conduit) or IMC (intermediate metal conduit), not EMT (electrical metallic conduit).
How long is a 2 inch EMT 90?
| Trade Size Metric Designator Offset (B)* | 2 53 1530 | 2 1/2 63 879 | 2 1/2 63 1041 | 2 1/2 63 1187 |

Why is a hickey called a hickey?
The origin of the word is from its earlier meaning of “pimple, skin lesion” (c. ... They can be covered with a concealer or powder corresponding to the sufferer’s skin tone, or a fake tan. Alternatively, articles of clothing such as scarves, snoods, turtle necks, or sleeves may be used to conceal hickeys.
What is a luminaire stud or hickey?
Luminaire (fixture) studs and hickeys are quite often installed in the same box, and where they are, they are counted as two conductors. ... Because there are different size conductors in the box, the luminaire (fixture) stud counts as one 12 AWG conductor, and the hickey counts as one 12 AWG conductor.
What is conduit or hickey pipe bender?
A hickey bender is used to bend conduit in small bends with short segments , for instance, in order to bend a 90° bend with this type of bender you would bend 9 each 10° bends with short gaps in between them. Another way to bend rigid or IMC conduit by hand is to use a full sweep bender for rigid or use an EMT bender.
How many bends are allowed in conduit?
National Electrical Code or NEC limits the total number of bends in one continuous run to 360 degrees or four 90 degree bends . It specifically states, “There shall not be more than the equivalent of four quarter bends (360 degrees total) between pull points, for example, conduit bodies and boxes.”
How do you calculate shrink in conduit?
To find out where to place the first mark on the conduit, multiply the measured Offset Distance to clear the obstacle by the tables Shrink/Inch that will occur to the conduit after all the bends are made due to that offset distance or: (Offset Distance) X (Shrink/Inch) = Total Shrink .
Can you bend conduit without a bender?
Flexible Conduit . If you don’t like the idea of bending electrical conduit then you can actually make this much easier and simpler if you use flexible conduit. This can be bend around into the right shapes without needing to use any form of bending or other solution.
