Glossary of Bending Terms with Illustrations
1. amount of offset — the dis-
tance that the conduit or pipe
must be re-routed to avoid an
obstruction; see offset in this
glossary and "Offset" bending
instructions in this manual
2. back-to-back bend — any
U-shaped bend formed by
two parallel 90° bends with a
straight section of conduit or
pipe between the bends
3. center-to-center distance —
the distance between the suc-
cessive bends that make
up an offset or a three-bend
saddle
4. depth of offset — same as
amount of offset
5. height of offset — same as
amount of offset
6. leg length — the distance from
the end of a horizontal section
of conduit or pipe to the bend;
measured from the end to the
center line, inside edge, or
outside edge of the conduit
or pipe
7. 90° bend — any bend that
changes the direction of the
conduit or pipe by 90 degrees
8. O.D. — the size of any piece of
conduit or pipe as measured by
its outside diameter

9. offset bend — two bends with
10. ram travel — the distance that
11. rise — the distance from the
12. shrink — the amount of conduit
13. springback — the amount,
14. stub — same as rise
15. stub-up — same as rise

the same degree of bend; used
to avoid an obstruction block-
ing the run of the conduit or
pipe
the ram of hydraulic bender
moves to accomplish a particu-
lar bend; inches of ram travel
are proportionate to degrees of
bend
end of a vertical section of
conduit or pipe to the bend;
measured from the end to the
center line, inside edge, or
outside edge of the conduit or
pipe
"lost" when laying out an
offset bend working toward an
obstruction; see the detailed
explanation under "Offset"
bending in this manual
measured in degrees, that
a conduit or pipe tends to
straighten after being bent
