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

local distributor nearby yeah hey thanks
for watching folks I'm wrong with the
ideal and I'll see you on the next one
