How To Make A Box Offset Bend



Sharing buttons:

that folks is wrong with the ideal in

this video I'm going to show you one way

to make a box offset better at a 1/2

inch piece of EMT conduit here using a

hand kind of better from ideal now a box

offset then is needed anytime an

electrician needs to feed an electrical

box with a piece of conduit like this

one over here okay and the deal is the

knockout on the side of the box it's not

flush with the back of the box

hence the cut it must be bent in a

slight shape like that so it could be

certain into the conduit fitting on the

side of the box now this allows the

Condit to be mounted flush up against

the wall or the concrete and without

putting any undue stress on the Condit

fitting or on the box itself now for

this demonstration I'm going to use our

catalog number 74 - oh 26 ductile iron

conduit better here for my deal now

ductile iron benders are typically

preferred by professionals as they will

last you longer then aluminum head

benders here which are lighter in weight

but they're also not quite as durable as

the ductile iron type vendors now

generally a 10 degree offset bin is used

to create this box offset is actually

two ten degree bends you're going to put

in two conduit and many contractors in

the field have done this enough that

they're just going to make a couple

marks on that content they're going to

have that offset bent before you even

know it okay but if you remember my

video on offset bends a certain shrink

amount and a certain multiplier is used

to create all of the different offsets

you're working with okay now on a 10

degree offset then the shrink amount is

only about a sixteenth of an inch for

every inch of obstruction you're going

to go over in the multiplier is six

which is going to be used to calculate

the distance between the two bins or the

two marks are going to make on my

conduct now on a typical electrical

outlet box the Knockouts about 3/8 of an

inch away from the back of the box now

that becomes the height of the

obstruction that we're going to need to

overcome okay so 6 times 3/8 of an inch

is two and a quarter inches and that

becomes the distance between the two

bins or the two marks I'm going to make

on this piece of conduit and in this

case the shrink amount is so small it's

not even a factor we weren't going to

worry about it okay now to make the Box

offset on the end of a piece of

automatically gonna make two marks on

the end of the conduit in step one is to

make the first mark about two and a half

inches to two and half inches away from

the end of the conduit if I make the

mark you know right close at the end of

the conduit of the hook on the bender

may actually deform the round shape of

the conduit and then the conduits not

going to fit inside the box or the

fitting that's on the side of the box

okay so contractors generally use a

pencil to make that mark on the content

so it can be a race letter down the road

in my example I'm going to use a

permanent marker and I'm going to mark

the conduit all the way around the

conduct and that way the mark on the

conduct will not get lost in the bender

head when I'm doing my bending here in

another minute or so okay now for the

three-eighths offset we calculated the

distance between the two bends to be two

and a quarter inches so I'm going to

make a second mark on my conduit at two

1/4 inches away from that first mark on

the conduit okay and again my mark the

conduit all the way around all right now

offset bends are done in the air not on

the ground so very simply you're going

to take your conduit bender you're going

to point the handle down like that with

the head kind of closer to you here and

then step two is insert that conduit

into the bender head you're going to

line up that first mark with the arrow

on the side of the bender okay they'd

bend your knees slightly like that kind

of lower your center of gravity place

one foot up against the bender boot

downer so it doesn't slide on you when

you make the bend and tilt the bender a

little bit away from me and then using

constant pressure I'm going to bend that

first bin to ten degrees now when do you

know you're at ten degrees well getting

the bottom of the conduit will be even

with that tend to remark on the side of

the bender head okay now step three is

to slide the conduit down to the second

mark okay and again line up the second

mark with the arrow on the side of the

bender head and then you're going to

rotate the conduit 180 degrees okay and

you're going to line up the two bends

use the handle on the bender here to

line up to two different bends and then

using constant pressure again would have

been that two again ten degrees okay

very good

now this creates the Box offset in that

conduit that allows that easily slide

into the kind of fitting on the side of

the box and knowing how to make a box

offset then quickly

and efficiently will make those jobs

from that much smoother and add value to

what you can actually do on those job

sites and again electricians don't bend

the Condit and then cut it to the

correct length once they know on how to

use a bender correctly the conduit is

the correct length for the end fit by

way for that particular job okay and

using good quality in conduit benders

like this one from ideal will provide

accurate and professional-looking bins

that electricians kind of expect when

they're out there in those job sites and

hand kind of benders from ideal please

customer service department to find a

local distributor nearby yeah hey thanks

for watching folks I'm wrong with the

ideal and I'll see you on the next one
