A. Rim notch/teardrop: Locates the center of a 3-point saddle bend. B. Arrow: Used to line up offset and outer marks for saddle bend.

What is the star mark on a bender used for?

The star on the conduit bender indicates the back of a 90-degree angle. This is used primarily for back-to-back bends so that both angles would line up perfectly.

Is the star or notch the center of the bend?

2. RIM NOTCH Locates center of saddle bend. 3. STAR Indicates the back of a 90° bend.

What is the teardrop on a conduit bender?

Each bender head features well defined, cast-in benchmark symbols professionals recognize like the arrow that points to the beginning of a bend, a star that indicates back-of-bend locations and the "tear drop" symbol which indicates the exact center of a 45° bend.

How many inches do you deduct for a 90 degree bend?

The most common deducts are 5" for ½" conduit, 6" for ¾" conduit and 8" for a 1" bender. It is a function of the curvature radius of the bender and cannot be changed. The deduct for your bender should be stamped on the bender.

How do you use 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 is Hickey 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.

When placing offset bends What mark on the bender do we use?

Most offset bends are made "in the air." This means the bender is used upside down with the handle on the ground and the bending foot in the air. Insert the conduit into the bender with the 38" mark positioned at the arrow normally used to bend a 90.

How do you mark conduit for bending?

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.

Which way should the Bender face when bending a stub up?

In order to make a stub-up of a specified length, the take-up mark must be aligned with the arrow on the bender, and the hook of the bender must face toward the end of the conduit from which the measurement was made.

Which mark on a hand bender is typically used as a benchmark for a 90 degree bend?

Star: The star mark is used when bending a 90˚ bend backwards.

Can you bend EMT with a Chicago bender?

The combination hydraulic benders, which can handle up to four-inch conduit (the maximum sizes of EMT and IMC conduit), are the most popular. With some models, users can make a full 90-degree bend in one shot or can use segment bending to make a larger sweep.

What is the stub for a 3/4 EMT?

Consider making a 14” stub, using a 3/4” EMT conduit. Step 1. The IDEAL bender indicates stubs 6” to ↑.

Why should sharp angles of bend be avoided when making offsets?

Sharp angles should be avoided because they will make it more difficult to pull the conductors. Whether a measurement is taken vertically or horizontally the amount of offset needed is called the ? .

What is a lamp hickey?

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.

What is offset bend?

An offset bend is a style of bend that is built independently of the 90° stub and the Back to Back bend and is an important bend to know when running conduit. It is common to shift the conduit a certain distance while continuing to run parallel in the same direction as the pre-shift portion of the conduit.
