that the conduit or pipe must be
re-routed to avoid an obstruction;
see offset in this glossary and
Offsets in Laying Out Bends in this
manual
2. back-to-back bend—any U-shaped
bend formed by two parallel
90-degree bends with a straight
section of conduit or pipe between
the bends
3. center-to-center distance—the
distance between the successive
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

same degree of bend; used to avoid
an obstruction blocking the run of the
conduit or pipe
10. ram travel—the distance that the
ram of a hydraulic bender moves to
accomplish a particular bend; inches
of ram travel are proportionate to
degrees of bend
11. rise—the distance from the 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
12. shot—a single bend
13. springback—the amount,
measured in degrees, that a
conduit or pipe tends to straighten
after being bent
14. stub—same as rise
15. stub-up—same as rise
