Measure length of bend (X). Subtract bender deduct
(see Table 1) from length (X) and mark this length from
the end of the conduit (Y). Line up (Y) with arrow on
bender. Bend until 90° bend is formed.
Table 1
Measure and mark distance on the conduit from a fixed
point (X), to the back of the 90° bend, point (Y). Align
(Y) with (B or ★) on bender and make a 90° bend.

Offset Bends
Measure height of offset (Z) and multiply by a constant
multiplier per angle of bend (see Table 2 on next page) to
determine distance between bends. Measure length (L) from
end of conduit to offset and add shrinkage (see Table 2 on
next page). Mark this length on conduit (Y). Subtract distance
between bends and mark point (X). Using arrow on bender,
make desired bend at point (X). Reverse bender and repeat
at point (Y).
