Glossary of Bending Terms with Illustrations
1. amount of offset—the distance
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 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

conduit or pipe as measured by its
outside diameter
same degree of bend; used to
avoid an obstruction blocking the
run of the conduit or pipe
the ram of a hydraulic bender
moves to accomplish a particular
bend; inches of ram travel are
proportionate to degrees of bend
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
measured in degrees, that a
conduit or pipe tends to straighten
after being bent
