Gardner Bender 910B Manuel De L'utilisateur page 9

Offset Bends
Measure height of offset (Z) and multiply by
a constant multiplier per angle of bend (see
chart below) to determine distance between
bends. Measure length (L) from end of
conduit to offset and add shrinkage (see
chart below). 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).
(For pre-determined values use chart on next page)
This chart is a guide for computing shrinkage.
Remember, shrinkage values are only used
when working into objects, not away.
