To locate distance between centers of offset bending marks other than
listed in table A use the following multipliers:
15° bend - 3.9
30° bend - 2.0
45° bend - 1.4

1. Table C shows minimum length (inches).
2. Mark #1 is stub length, deduct from this as per table C
and obtain mark #2.

5.0 ANGLE ADJUSTMENT
Two different type scales are mounted on the shoe outer rim.
One for
1
⁄2" thru 2" IMC and Rigid, the other for EMT
1
⁄2" thru 2"
See Figure 12.
Each scale indicator is adjustable to compensate for over long
or short bends which may be due to differences in conduit
characteristics or other variations.

Figure 12. Two Type Scales
Bends which are too long: Loosen the size scale (for type material
being bent) mounting screws. Slide the scale clockwise as many
degrees as the overbend (if bend is 5° over, move indicator 5°
clockwise). The degree of movement is observed by watching one
of the size marks as it moves past the angle disc scale. Tighten
the mounting screws.
Bends which are too short: Loosen the size scale (for type material
being bent) mounting screws. Slide the scale counterclockwise
as many degrees as the bend is short (if bend is 5° short move
counterclockwise 5°). The degree movement is observed by watching
one of the size marks as it moves past the angle disc scale. Tighten
the mounting screws.
